When is the dangerous period for menstruation on the 28th?

People often say that the safe period of menstruation can be a contraceptive measure. According to scientific research, the safe period of menstruation is our ovulation period. During this time, our body releases an egg, waiting to fuse with sperm, which is the process of procreation. If you don't want to get pregnant, you should avoid having sex during this time. So, how many days after the menstrual period is the dangerous period for pregnancy?

A few days after the menstrual period is the dangerous period for pregnancy

1. The safe menstruation period is the old saying seven days before and eight days after menstruation. 7 days before and 8 days after menstruation are safe, but this is just a basic rule. Generally speaking, the safe menstruation period before ovulation is 7 days, and the safe menstruation period after ovulation is 8 days. If your menstrual cycle has always been 28 days, you can arrange it according to the first seven and the last eight, because this can bypass the 10-day dangerous period of pregnancy.

2. For a woman who often has short cycles, for example, a cycle of 21 days, then the ovulation period is approximately on the 7th day. At this time, there is no safe period before ovulation to talk about, because you may encounter the minimum pre-ovulation period just after the menstrual period ends at any time. For such women, there is still a risk of pregnancy even if their menstrual period has just ended.

3. For a woman who often has a long cycle, for example, a cycle of 35 days, then the ovulation period is around the 21st day. The often delayed ovulation at this time will make it impossible to determine the safe period of menstruation after ovulation.

4. The ovulation period calculation method is: start counting from the first day of the next menstruation, and count for 14 days or minus 14 days, which is the normal ovulation period of women. Then add the ovulation period and the 5 days before and 4 days after it together, which is called the female ovulation period. If female friends want to get pregnant as soon as possible, they need to clearly calculate their ovulation period. Only in this way can they get pregnant and give birth normally.
