Do I need to take medicine if the chance of pregnancy is 15?

A woman's month can be divided into a safe period and a dangerous period. The safe period mainly refers to the non-ovulation period. Having sex during this period will reduce the woman's chance of pregnancy. However, for couples who have no intention of getting pregnant, if they have sex, they still need to take contraceptive measures, because there is a possibility of pregnancy even if they have sex during the safe period. So some women may wonder if they need to take medicine if the chance of pregnancy is 15?

Generally, medical abortion can be chosen within 49 days of pregnancy. However, medical abortion has great side effects and can easily lead to incomplete abortion. It also requires uterine curettage, which can cause great damage to the uterus. It is safer to choose painless abortion. The best time for abortion is 6-10 weeks.

Having sex during ovulation is the easiest way to get pregnant, with a chance of over 90%. The reasons why some normal and healthy couples have a lower chance of conceiving are: First, the egg is fertilized: the couple's sexual life may not occur before or after ovulation, thus missing the fertilization period of the egg. The second is that the egg is fertilized by multiple sperm: It is not common for the egg to be fertilized by multiple sperm in the body, but if too many sperm reach the fertilization site of the fallopian tube, polyspermy is still possible.

Polyspermy prevents the egg from developing and implanting normally, and therefore pregnancy cannot occur. Third, the formation of aneuploid embryos: the formation rate of aneuploid embryos in humans is very high. If the only embryo in a cycle is aneuploid, the chances of pregnancy are almost non-existent. Moreover, the formation of aneuploid embryos is proportional to the age of the woman.

This also explains why it is more difficult to get pregnant as you get older. Aneuploid embryos are extremely harmful and can cause fetal deformities and miscarriage in patients. Patients can only conceive a healthy baby through the third-generation IVF technology PGD pre-transplant embryo genetic screening. Fourth, women’s health is poor: excessive fatigue, lack of rest, excessive stress, mental and emotional instability, etc., cause the body to be not in the best condition, and the endocrine environment is temporarily disordered. The egg was fertilized, but implantation did not occur.
