How many days after menstruation can you have sex without getting pregnant?

Many female friends usually use calculation of ovulation period to prevent pregnancy. This is mainly because female eggs have a certain cycle and their survival period in the female body is also very limited. As long as the ovulation day is avoided, the possibility of pregnancy will be greatly reduced. Let us understand some of the main reasons why women will not get pregnant after having sex a few days after menstruation.

Generally, we calculate the ovulation period as about 14 days before the next menstruation. After the egg is released from the ovary, it can survive in the fallopian tube for 1-2 days to wait for fertilization; the male's sperm can maintain fertilization ability for 2-3 days in the female's reproductive tract, so it is easy to get pregnant by having sex a few days before and after the egg is released. To be on the safe side, we call the 5 days before and 4 days after ovulation, together with the ovulation day, a total of 10 days, the ovulation period.

If your menstruation is regular, you can use an ovulation test strip 2 days before and after ovulation. If two red lines are detected, it means ovulation is about to occur, and you can have sex on the same day or the next day. It is easy to get pregnant during the ovulation period, so the ovulation period is also called the fertile period or the dangerous period.

Best time to conceive

A woman's chances of getting pregnant are highest when she has sex during her ovulation period. But how do you know when your ovulation day is? You can refer to the following two methods:

1. Schedule calculation method

Generally speaking, a woman's ovulation day is 12-16 days (14 days on average) before the next menstrual period. The specific date can be calculated using the calendar extrapolation method. The main method is to calculate the fertile and infertile periods in the current cycle based on the records of more than 12 previous menstrual cycles. The formula is as follows:

1) The number of days in the shortest cycle in the past - 19 = the last day of the infertile period before ovulation. The next day is the first day of the fertile period.

2) The longest cycle in the past - 10 = the last day of the fertile period after ovulation. This way you can calculate the exact date of your fertile period.

Women with normal menstrual periods usually have a cycle of 28 days. Women can calculate their schedule based on their menstrual patterns.

The few days before and after the menstrual period are relatively safe, but it is impossible to completely rule out the possibility of pregnancy. If you are not ready to have a child for the time being, it is best to take some safer methods of contraception to avoid accidental pregnancy, which may cause great harm to the female body during surgery.
