First trimester: Dangerous for the baby

There is a tradition of never announcing your pregnancy until the first 3 months have passed and the reason is very simple: The first trimester is the most dangerous for the baby and there is a high possibility of losing the pregnancy, but… #KnowledgeIsSuccess and in this video Dr. Carlos Monsalve, expert in Maternal-Fetal Care at Creafam, explains exactly what happens and what we can do to reduce the risks.

Choose how many weeks pregnant you are

Risk #1: Implantation

We have already mentioned in several videos that a healthy and fertile couple will take an average of 6 months to achieve pregnancy, but here comes the curious thing: most couples think that if they do not get pregnant the first time, it is because the sperm did not manage to fertilize the egg, but the truth is that if they have sex on their fertile days, fertilization will most likely be successful. However, it is estimated that more than half of the embryos are lost in the first week because they do not manage to implant correctly in the uterus and therefore menstruation is not even missed.

What can we do to help the embryo to implant? Dr. Arturo Valdés and Biologist Luis Machorro already have a video that explains a little about how to improve the quality of the eggs and sperm. It is a little more focused on fertility before achieving pregnancy, but I recommend that you take a look at it.

Meanwhile, from the point of view of obstetrics, that is, maternal-fetal care, I usually prescribe a little progesterone because this hormone will help the sac to better attach to the endometrium. Please do not self-medicate, fortunately an excess of progesterone will not affect your baby but it could cause you a lot of: weakness, drowsiness, nausea, blurred vision, difficulty breathing, chest pain, swelling, heart problems and even depression.

So, it is not a good idea to take progesterone just for the sake of it. Come to a consultation, we will check how your endometrium is and in this way we will help that baby to move forward.

Risk #2: Bleeding

Around week 3 of the menstrual cycle and if the embryo manages to implant, the next thing to worry about is any bleeding. I repeat as always: No discharge or bleeding is normal during pregnancy.

“Hey! But someone told me that it is normal to have bleeding and it is called implantation bleeding.”

No! Please, no. In fact I don’t know why they call it implantation bleeding, it should be called implantation spotting and it doesn’t happen at any time, it is a spotting that occurs just on the day that your period was due. The endometrium is not perfect and although the signal that there is a pregnancy was received, probably a small section of the outermost layer came off somehow and that caused a spotting. It is a faint spotting, like pink or brown and it is not a law that it has to happen, only some women have that spotting and for many that spotting is the first sign that they are pregnant.

If you are already several weeks pregnant and suddenly start having heavy, flowing, deep-colored bleeding, don’t think twice, go for a consultation immediately.

Risk #3: Ectopic pregnancies

When your period is delayed by a full week, it means that you are technically already five weeks pregnant. Remember that in obstetrics we start counting the weeks of pregnancy from the first day of your last period. Don’t let time pass, as soon as you notice this delay go buy a pregnancy test at the pharmacy, they are usually very cheap and very accurate.

Pregnancy tests work by detecting the hormone human chorionic gonadotropin, which is released by the embryo to stop menstruation and start pregnancy. When the embryo is well implanted inside the uterus, it manages to release large amounts of this hormone and the lines on the pregnancy test look very colorful and marked. When the embryo is implanted outside the uterus, it is called an ectopic pregnancy and it does not manage to produce as much hormone, therefore, the second line on the pregnancy test looks very faint and weak.

Now, having a very thick and colorful line is not a guarantee of a good implantation. Sometimes mothers come who took the pregnancy test up to three or four weeks later, and of course, the embryo is already larger and even though it is outside the uterus it produces more hCG, that is why I recommend taking the pregnancy test as soon as possible.

Remember that the ultrasound can be done practically from the first day of pregnancy, it does not affect your baby and it is the best way to confirm if the embryo is well implanted.

Risk #4: Anatomical defects

Another advantage of performing ultrasound is that it helps us identify if there are anatomical defects. One of the most common is called Asherman’s syndrome and basically refers to the existence of adhesions in the internal walls of the uterus. They usually appear after severe infections, MVAs or some scrapings. In some cases, the adhesions are so severe that they prevent the endometrium from developing, affecting fertility.

Other common defects are polyps and fibroids. These are abnormal growths of the endometrium and uterine muscle, respectively. Unfortunately, if the embryo implants on top of these growths, it is very likely that it will not develop correctly and will die within a few weeks. There is not much we can do about it during pregnancy. With some luck, we can give nutritional supplements and help the placenta to grow and develop quickly, but if the pregnancy is lost, it would be advisable to operate on the polyps or fibroids before trying to get pregnant again. I am often asked if ovarian cysts affect pregnancy, and no, they really don’t.

Ovarian cysts and polycystic ovary syndrome can reduce the chances of getting pregnant, but if you have already managed to get pregnant, don’t worry! Nothing will happen to your baby, and if for some reason your doctor suggests surgery for your cysts during pregnancy, please seek a second opinion, come see us, because there is no point in putting your baby at risk.

Risk #5: I didn't know I was pregnant

Most mothers know that during pregnancy you should not smoke, drink, self-medicate, take drugs, expose yourself to chemicals or toxins, that you should not take x-rays of the abdomen and that you should moderate your consumption of coffee, tea, foods with excess sodium, sugars and preservatives, but here comes one of the most common risks… I didn’t know I was pregnant.

The good thing is that babies are very resistant and exposure to these substances does not usually cause fetal death, the bad thing is that many women then think that nothing bad is happening, in fact at least once a month, I come across a comment on YouTube from a mother claiming that even if she took drugs or smoked every day her baby was born very beautiful and without deformities.

And yes, that’s right! Exposure to these substances is not going to cause your baby to lose an ear or grow three arms, but little by little they will realize the problems with their behavior. They are babies who are dependent on substances and that is why they cry a lot, even if they are not hungry or sleepy and are clean, they continue crying for no apparent reason. As children they can have attention problems, they are problematic teenagers and as adults they are more likely to develop addictions or conditions such as diabetes.

The absence of the menstrual period is a good sign of pregnancy for most women, usually only those who suffer from irregular periods are those who do not realize they are pregnant, so my recommendation, especially if you suffer from polycystic ovary syndrome or hormonal imbalances, is to always be alert to other signs of pregnancy such as: nausea, increase in the size and sensitivity of the breasts, being very tired or sleepy and of course… unusual cravings. If you suddenly feel like eating something you have never liked very often, take a pregnancy test!

Risk #6: Infections

The next risk is very important and it is about infections. It is a little sad, but I think that half of the new patients who have never come to a consultation, come for the first time because they have an infection that has already gotten out of control. They come and tell me that they have been on treatment for a few weeks, and obviously, I ask them what type of infection they have and they tell me that they don’t know, but that they have already bought this cream or this ovule and it hasn’t worked for them.

And that is the crux of the matter! That an infection can be due to viruses, bacteria, fungi and of course, even when we talk about bacteria there are hundreds of probable bacteria.

Remember, we say it in every video: Knowledge is power and the first step is to have the correct diagnosis, get a urine culture, a vaginal culture, it is cheap, fast and can save your baby’s life.

Risk #7: HR incompatibility or blood incompatibility

The next risk is blood incompatibility, which is more common in the second and third trimester, but we are referring to when the mother has RH-negative blood type and her partner has RH-positive blood type. No other combination is going to worry us, it’s not a problem. The only one that causes problems is the mother being RH-negative and the father being RH-positive, because there is a 50% chance that the baby will be RH-positive like the father and then the mother’s immune system can attack the baby.

If you don’t know what type of RH you have, please get tested as soon as possible and if you already know that as a couple you have incompatible blood type, don’t worry, we can give you a vaccine to prevent the immune system from attacking and everything will be fine.

Risk #8: Poor nutrition

Being overweight can cause complications for the mother’s health, especially in the third trimester, but during the first trimester the real danger for the baby is when the mother is underweight, because usually that means that the endometrium is very thin and the placenta will have problems absorbing nutrients, it could even detach, which, if the placenta detaches, the pregnancy is lost immediately.

Remember that during pregnancy it is important to have a balanced diet, preferably small portions but more often, eating up to five or six times a day and although there are nutritional supplements and vitamins, nothing beats getting nutrients naturally. Every day you should eat fruits and vegetables, milk and its derivatives, carbohydrates whether in pasta, bread, tortilla or seeds, eat meat and eggs, drink a lot of water… Pure water, not sugary drinks.

Risk #9: Strong blows or accidents

Returning to the reasons why it is worth telling others that you are pregnant, we come to danger number nine: Strong blows.

Fortunately, the embryo is wrapped in a gestational sac, floating in amniotic fluid, surrounded by the muscles of the uterus and protected by the pelvis, at least on the sides and back. In fact, it is very unlikely that a push or a bump will affect it, but you should not exaggerate.

If you have a severe blow or a traffic accident, it is worth performing an ultrasound, but pay attention and notify your doctor of the blow, because it is not just a matter of checking the baby, it is more likely that the blow has affected the placenta and you should check if there are no bruises or signs of detachment.

Now, if you have ever suffered physical violence in your home, please seek help immediately. Statistically, you are almost three times more likely to suffer a miscarriage, do not stay still, seek help.

Risk #10: Repeated abortions

When a pregnancy is lost after week 12, we call it gestational loss, and it is usually due to a lack of care because it can usually be prevented, we can detect that something is wrong and take precautions, but when death occurs before week 12, it is usually due to problems with the baby’s health.

If you had a good implantation, if you had no bleeding or anatomical defects, if you fought infections, if you ate well, if you were not hit and followed the doctor’s instructions to the letter but still lost your baby before week 12, do not be overwhelmed, do not think that you are bad mothers or that there is something wrong with you. It is normal, 1 or 2 out of 10 pregnancies end in miscarriage before week 12, however, if it happens to you again it is considered a repeat miscarriage and if you have a third miscarriage, the chances of a repeat miscarriage are higher than 85%.

In these cases, it is almost certain that there is a genetic defect in the embryo, so it is worth doing genetic studies, first of all on the sperm, the sperm FISH and if everything is fine with the sperm, then we have to do the salivary DNA study, that will tell us if you mothers are developing blood clots during pregnancy. If you have altered salivary DNA and are generating blood clots, do not worry, you can get pregnant but at the beginning of the pregnancy you have to give medical treatment.

If there are genetic or chromosomal defects, then yes, doing in vitro fertilization with genetic diagnosis would be advisable. We receive many patients who suffer from repeated miscarriages and in 9 out of 10 cases we can achieve a successful pregnancy.

Farewell

I hope that all this information has helped you to take better care of your pregnancy. I’ll see you in the next video that will be about the third trimester, because in that case the opposite happens. The baby develops quickly and without problems, but the more the baby grows, the more complications and risks the mother may have. I say goodbye wishing that you soon have your dream come true in your arms.

Come see us, together we can provide the best maternal-fetal care for your pregnancy.
