Because there is no fetal heart after 40 days of pregnancy, there are several ways to check the quality of embryos during this period.
The first is to draw blood to check progesterone and HCG. In particular, it is better to check that HCG is doubled.
What is the Chinese name of HCG? Human chorionic gonadotropin? It is a glycoprotein secreted by placental trophoblast cells. Usually, better-developed embryos secrete HCG faster. Therefore, doctors can judge the quality of embryos by taking blood every 48 hours to check the growth of HCG. Under normal circumstances, HCG will increase by more than 67% every 48 hours, which is a relatively normal range. In other words, if the HCG index rises above 67% two days after blood drawing, it means that the embryo development is not bad.
Progesterone is generally used as a reference index. Usually, the normal value of progesterone in the body after pregnancy is more than 32 to 60. If progesterone is too low, it may lead to fetal arrest or threatened abortion. Some pregnant mothers have relatively low progesterone, but as long as it is within the normal range, there will be no major problems. However, it is better to follow the doctor's advice after each blood draw.
The second method is to observe the reaction of early pregnancy, which can only be used as a reference. However, because the early pregnancy reaction of some pregnant mothers is not obvious, it does not mean that the embryo is stunted. And if it is a pregnant mother with obvious early pregnancy reaction, generally speaking, embryo development is better.
Third, we should always pay attention to the performance of abdominal pain. At the beginning of pregnancy, when the fertilized egg is implanted, the more sensitive pregnant mother will feel a tingling sensation in the abdomen or a feeling of abdominal pain. Normal is the physiological pain during pregnancy, and its degree of pain is so low that many pregnant mothers don't even feel it. If you feel obvious or severe abdominal pain or even redness in the first trimester, there is the possibility of threatened abortion, so you should seek medical advice in time.
Finally, we can do B-ultrasound to check the embryo development. Although there is no fetal heart and germ at 40 days of pregnancy, can you pass the B-ultrasound examination at this time? Intrauterine pregnancy? , timely discover abnormal situations such as ectopic pregnancy. At the same time, by checking the size of the gestational sac at this time, it can also help to judge whether the embryo is developing well. Of course, due to the different situation of each pregnant mother, the specific results of B-ultrasound examination are subject to the doctor's diagnosis suggestion.
In short, after 40 days of pregnancy, the quality of embryo development can be checked by blood drawing, self-observation and B-ultrasound. However, pregnant mothers in this period still focus on relaxation and let nature take its course. Don't give yourself too much psychological burden.
