Pregnant women all hope for the healthy and happy growth of their babies in their stomachs, but sometimes this is not necessarily the case because some women may experience biochemical pregnancy after pregnancy, resulting in the inability to preserve the fetus. So, how many days after ovulation does biochemical pregnancy usually occur?
Biochemical pregnancy usually occurs around 40 to 45 days after pregnancy and starts counting from the first day of a woman's last menstrual period. That is to say, biochemical pregnancy usually begins one month after a woman becomes pregnant, which is also the time when the woman's pregnancy can be detected.
Under normal circumstances, the fertilized egg formed by the combination of sperm and egg will implant in the uterus around the seventh day, and implant into the endometrium of the uterus to form an embryo, thus developing normally in the female uterus. However, biochemical pregnancy is different. The fertilized egg of biochemical pregnancy does not implant into the endometrium of the female uterus, but flows out of the body with menstruation, resulting in miscarriage.
The detection of biochemical pregnancy is relatively simple because it takes about 14 days from successful implantation of the fertilized egg. During this process, if early pregnancy test strips are used for examination, a weak positive result will be detected, and the weaker the positive expression, the more likely it is to indicate the occurrence of biochemical pregnancy.
Because under normal circumstances, the results detected by early pregnancy test strips are positive and gradually increase, without becoming weaker. Therefore, one can make a judgment based on this characteristic. However, if it is not so certain, one can also go to the hospital for further examination to see if there is a biochemical pregnancy.
