After pregnancy, many people will go to the hospital to check progesterone and HCG, are these two indicators important? Of course they are important! It gives us an indication if we are pregnant and may be able to predict whether the pregnancy is normal or not and whether it will be successful! The dynamic indicators are even more important! A very low value could be an ectopic pregnancy or a miscarriage! Will a high value prevent a miscarriage? What else can happen? The HCG doubles well but the progesterone drops. This means that the embryo is developing normally, but the HCG progesterone function is not working. This is a case of waiting, as long as the progesterone is not particularly low, it is possible to continue the pregnancy without supplementation. Some progesterone tests do not really reflect the level of progesterone in the body. The second situation is that the progesterone is normal, but the HCG doubling is not good. Because HCG promotes the production of progesterone, if HCG is bad, progesterone is generally bad. We will specify the following two situations: 1. progesterone is normal, but HCG doubling is “relatively” bad. What does it mean? It means that when you go to test one day, the value goes up but not to the multiple, it’s not as good as a hundred or two hundred, that’s relatively bad. If your HCG is already tens of thousands, then the doubling is not so fast and the speed will drop, which is normal. 2, progesterone normal, HCG doubling “absolutely” bad. Absolutely not good, is the value in a range, let’s say 8 days, only doubled, this situation is not very good. The first thing to do is to rule out ectopic pregnancy, and then there may be a problem with the embryo. Nowadays, many hospitals only supplement progesterone, but rarely supplement HCG, because low HCG is likely to be bad for the embryo itself, and it is not very valuable to preserve the fetus. The HCG is not doubling but decreasing, and the progesterone is also decreasing, this situation doctor is recommending you to keep the fetus, if there is still no improvement after taking the fetus preservation measures, it is also recommended that you give up as soon as possible and do abortion. In this case, it is very likely that the embryo itself is not good and there is no point in keeping the fetus. If you force to keep the fetus, even if the fetus is successfully kept, the fetus will face more tests in the later pregnancy, and even suffer from fetal abortion, which will increase the risk of the mother-to-be when she has an abortion later. HCG and progesterone work synergistically to protect the fetus. HCG starts to be produced by the body six days after pregnancy, when the fertilized egg is ready to be laid, and HCG will stimulate the body to produce progesterone. Progesterone is about to ensure that the internal environment of the uterus is stable and minimally disturbed by external forces, which also protects the embryo. Generally speaking, HCG is doubled every other day in the early stages, so there are no people who take HCG test every day, but usually every other even numbered day, let’s say 2, 4, 6, 8 days. The synergy between HCG and progesterone is to provide nutrients to the embryo on the one hand, and to ensure the safety of the embryo on the other hand, so one is indispensable; if the HCG doubles badly, the embryo may develop slowly or even stop because of the lack of nutrients; if the progesterone is not enough, the embryo will be unstable in bed, causing bleeding or even miscarriage. However, low HCG and progesterone values do not necessarily mean miscarriage, but only a higher chance. Once bleeding occurs, you should go for a test, and if you have a history of bad pregnancy before, you can monitor it just in case. Not all bleeding means miscarriage. There are some issues worth noting: first of all, the brown discharge, some people think it is bleeding and go to the hospital to find a doctor to prescribe progesterone to eat, but in fact it is not. Pink, bright red, non-sticky, heavy bleeding or continuous bleeding is the only thing that needs to be taken into account if it is a miscarriage. This brown discharge usually has a small amount for two or three days and then it passes and does not come back. Secondly, the bleeding after pregnancy is from the urethra, vagina, and cervix, and is not directly related to miscarriage, so you must go to the hospital for a gynecological examination and urinalysis to diagnose this situation. Don’t be afraid of gynecological examination during pregnancy, otherwise it will cause unnecessary tension or delay the diagnosis, cervical cancer in pregnancy is not uncommon! Extended knowledge: About progesterone for fetal preservation The use of large amounts of progesterone in early pregnancy can increase the risk of malformations in the fetal spine, anus and limbs by 8 times. If synthetic progesterone is used (e.g., kynurenine has androgenic effects), about 18% of women have masculinized fetuses. And the use of progesterone under normal conditions of progesterone deficiency does not pose a risk, so we must have a correct understanding of progesterone, the different factors of miscarriage, and the right understanding of fetal preservation to avoid good intentions. How to supplement progesterone is correct First of all, we must find out whether there is a lack of progesterone. The lack of progesterone can be confirmed by laboratory tests and also by measuring the basal body temperature. For those who are indeed luteal deficient, progesterone can be injected from 3-4 days after the basal body temperature rises in order to conceive, and used uninterruptedly for 9-10 weeks until the mother can naturally produce progesterone.
