Can a woman get pregnant if she has sex on the third day after her period ends?

Nowadays, many girls don’t particularly understand what the safe period or the dangerous period is. Therefore, sometimes having sex before or after menstruation can lead to pregnancy. I believe everyone is very curious about when are the safe period and dangerous period for girls? Let me take you to understand it.

The safe period refers to the 1st to 7th day of the menstrual cycle and the last 4-5 days of the cycle. During this period, ovulation has not occurred or the egg has died, so even if the ovulation date changes, it is still an absolutely safe period. From the perspective of contraception, they divide a menstrual cycle into an absolutely safe period, a safe period and a dangerous period. However, depending on each person's specific situation, early ovulation or double ovulation may occur.

Assuming a menstrual cycle (from the first day of menstruation to the first day of the next menstruation) is 28 days, ovulation occurs around the 14th day. The 3-5 days before and after ovulation are the fertile period, which is a dangerous period for contraception. Days 1-7 and the last 4-5 days of the cycle are when ovulation has not occurred or the egg has died, which is an absolutely safe period. The remaining days are relatively safe periods, because ovulation may be advanced or postponed a few days due to many factors, so it is called relatively safe.

If you have sex during the absolutely safe period, it is almost impossible to get pregnant, unless there are extremely special circumstances where there are 2 or more ovulations in one cycle; if you have sex during the relatively safe period, the chance of contraceptive failure is greater. Many people think that safe period contraception will not affect sexual pleasure and is very convenient, so many young women are keen to use this contraception, and many women who have just given birth also rely on calculating the safe period to prevent pregnancy.

After sperm enters the female reproductive tract, it can maintain its fertilizing ability for 1 to 3 days. Therefore, a woman is more likely to become pregnant if she has sex with a man from 3 days before to 1 day after ovulation. If either the sperm or the egg has lost its ability to fertilize when they meet, conception will not occur.

I believe everyone now has a clear understanding of what the safe period and the dangerous period are, so sometimes if you do not take emergency contraceptive measures, you can also avoid pregnancy by calculating the safe period and the dangerous period. However, it is still better to take contraceptive measures. Contraceptive measures can not only reduce the success rate of pregnancy, but also effectively prevent the spread of other diseases.
