There is a kind of pregnancy called "biochemical pregnancy", and this fetus is destined to stay!

My period didn't come. Bought early pregnancy test paper, two columns. My husband is also very excited. I'm pregnant for the first time in my life, and I'm going to celebrate. But I didn't expect a biochemical pregnancy every few days, and it was abrupt. It's a bit like in a previous life, the rest of the reason consulted a doctor and was told to live.

I can't figure out why there is biochemical pregnancy. Feel healthy, no bad habits, regular menstrual cycle, normal pre-pregnancy examination.

1. What is biochemical pregnancy?

Early abortion in the fifth week of pregnancy refers to the phenomenon that * * * fails to be transported to the uterine cavity for implantation after being combined with the egg, and then miscarries with menstruation.

* * * combined with the egg to form a fertilized egg, which began to implant on the 6th to 7th day after fertilization, differentiated into trophoblast on the 9th day, and completed the secretion of HCG human chorionic gonadotropin on1~12 days.

There are three stages of implantation: positioning, attachment and implantation. There are problems in any stage, which may lead to failure. Biochemical pregnancy means that the HCG value is greater than the normal range, and it can be detected in the blood (> 25 mlu/ml) or the urine pregnancy test is positive, but the gestational sac can't be seen by ultrasound, which indicates that the fertilized egg failed to implant and then the pregnancy state naturally terminated, also known as "subclinical abortion".

Second, what are the manifestations of biochemical pregnancy?

The bleeding time of biochemical pregnancy roughly coincides with the menstrual time, or is delayed by several days; It's hard to feel it without an early pregnancy test.

The amount of bleeding is almost the same as the usual amount of holidays, or slightly increased. Intentional female friends measured two bars with early pregnancy test paper, and there were early pregnancy reactions, such as chest tightness, acid reflux, nausea, and increased HCG value in blood. But after a few days, a faint watermark appeared on the early pregnancy test paper, and the blood HCG value and progesterone value decreased. After that, it was almost like a holiday, and my stomach was a little uncomfortable, like a faint menstrual pain. There are also women who have no feelings. If you pay attention to blood, you will find something like light carrion.
