A few days after the big aunt is safe

summary

A few days after the big aunt is safe. I believe that in addition to male friends, we are female friends. Female friends come to the big aunt once a month, but many friends don't know that the next few days after the big aunt is a safe period, which sometimes leads to pregnancy. Let me tell you that the next few days is the safety period.

A few days after the big aunt is safe

First of all, a few days after the big aunt is safe, women's ovulation date is generally about 14 days before the next menstruation. After the egg is discharged from the ovary, it can survive in the fallopian tube for 1-2 days to wait for fertilization; the sperm of a man can maintain the ability of fertilization for 2-3 days in the reproductive tract of a woman, so it is easy to conceive during sexual intercourse within a few days before and after the egg is discharged

Then, a few days after the big aunt is the safety period, which is divided into pre ovulation safety period and post ovulation safety period. The period from the day when menstruation is clean to the day before ovulation is the safe period before ovulation. From the first day after the end of ovulation to the day before the next menstruation is the safe period after ovulation.

Sometimes ovulation before and after the environment is not safe to shorten the last few days, and so some women will not know the safety of ovulation. Ovarian in a menstrual cycle has two egg row is very rare, that is, ovulation to the next menstrual cycle before this period of time generally will not occur the second ovulation, so, after ovulation safety period is relatively safe.

matters needing attention

The key of using safe period contraception is to determine the date of ovulation. When ovulating, there is no special feeling. Even if some women may have abdominal pain, backache, breast swelling, emotional changes and other symptoms, these phenomena are not the specific symptoms of ovulation, so they can not be used as the basis for ovulation.
