Medical abortion without fertilized egg implantation

Girls who have an unexpected pregnancy will have medical abortion to prevent the pregnancy from continuing. There are certain requirements for the use of medical abortion. Generally, the age of pregnant women should be under 40 years old and the pregnancy time should be less than 49 days. When the fertilized egg has not yet implanted, it has not yet fully developed. Its development is extremely unstable at this time. If you have a medical abortion at this time, it is very likely to fail to develop and be expelled from the body with menstruation.

Generally speaking, after the sperm and egg combine, they will successfully implant and develop on the endometrium after a few days. However, not all fertilized eggs can successfully implant and develop on the endometrium. The quality of sperm and egg is important, but the internal environment of the uterus is also very important. There is always a way out, so symptoms of failure of fertilized egg implantation also occur from time to time.

Symptoms of failed implantation of fertilized egg

The possibility of conception is higher one week after ovulation, but pregnancy is not certain. It is affected by many factors such as the amount of semen and body position, and a fertilized egg may not necessarily appear. Even if the egg is successfully fertilized, whether it can implant successfully depends on the state of the endometrium, so it is possible that the fertilized egg cannot implant normally, resulting in pregnancy failure.

If implantation does not occur normally, then it will be no different from a normal menstrual cycle. Under the action of hormones, the endometrium that has thickened will peel off and bleed, forming menstruation, and then entering the next menstrual cycle.

If the fertilized egg has not implanted, it will not fall off. In the early stages of pregnancy, the gestational sac may fall off easily due to poor development or lack of attention in life, resulting in miscarriage. If the gestational sac is implanted, it will not grow and may be absorbed by itself in the uterus. Vaginal bleeding in early pregnancy should be considered as a possible sign of threatened abortion or ectopic pregnancy.

Reasons for the failure of fertilized egg implantation

1. The fertilized egg itself is defective

Most of the time, it is always healthy sperm that combines with the egg, but in some special cases, some abnormal sperm will combine with the egg first. Sometimes, after the egg combines with one sperm, a second sperm also combines with the same egg, and the fertilized egg formed in this way has congenital defects. Therefore, before pregnancy, both husband and wife should check whether their chromosomes are abnormal so that a healthy fertilized egg can implant successfully.

1. Imperfect ovarian corpus luteum function, insufficient progesterone secretion, and endometrial abnormalities affect the implantation of the fertilized egg.

2. Some women have been married for many years and have normal sex life, but cannot get pregnant. It is very likely because the corpus luteum of the ovary is not functioning properly, progesterone secretion is insufficient, and the endometrium is abnormal, which affects the implantation of the fertilized egg.

The symptoms of failed implantation of the fertilized egg are not obvious, because the implantation of the fertilized egg itself is a silent process and there is no abnormal condition. Therefore, even if the fertilized egg fails to implant, there will be no abnormal situation. It’s just that after the fertilized egg fails to implant, the endometrium will shed regularly as usual, and then the menstruation will come.
