Can you get pregnant before your period?

In order to get pregnant, many women always calculate their ovulation period, and the success rate of conception during the ovulation period is relatively high. The calculation of ovulation is based on the time of menstruation. Except for the dangerous period during ovulation, the rest of the time is the safe period. Usually, pregnancy will not occur during the safe period. Female friends who don’t know how to calculate time will ask, can you get pregnant if you have sex before your period?

The menstrual period and the few days before and after menstruation are safe periods and you will not get pregnant. Women's menstrual cycles vary in length, but the interval between ovulation and the start of the next menstruation is relatively fixed, usually around 14 days. The calculation method is to count from the first day of the next menstrual period, and count down 14 days or subtract 14 days to get the ovulation day. The ovulation day and the 5 days before and 4 days after the ovulation day are called the ovulation period. For example, a woman's menstrual cycle is 28 days. The first day of this menstruation is June 2nd. Then the next menstruation will be on June 30th (June 2nd plus 28 days). Subtract 14 days from June 30th, and June 16th is the ovulation day. The ovulation day and the 5 days before and 4 days after, that is, from June 11th to 20th is the ovulation period. In addition, in the menstrual cycle, except the menstrual period and ovulation period, the rest of the time is the safe period. So there is a safe period before ovulation and a safe period after ovulation in the menstrual cycle. In fact, this is also the theoretical basis of the safe period contraceptive method.

However, to calculate the ovulation period using this method, you must first know the length of your menstrual cycle in order to calculate the exact time of the next menstrual period, and then calculate the ovulation period. Therefore, this method is only suitable for women with normal menstrual cycles. For women with irregular menstrual cycles, it is impossible to calculate the date of the next menstrual period. Therefore, it is impossible to calculate the ovulation day and ovulation period.

Generally, you will not get pregnant if you have sex one week before or after your period because you are within the safe period. For women with regular menstrual cycles (calculated as 28 days), the safe period is about 14 days before the next menstrual period. If the cycle shortens, the 14 days will also be shortened accordingly. However, the safe period is not absolutely safe. It can only be said that the probability is small, because many women with irregular menstrual cycles also have irregular ovulation. Therefore, the safe period is not absolutely safe.

After the above introduction, we know how to calculate the ovulation period and the safe period, and we also know that the week before and after the menstrual period is a safe period, and you will not get pregnant if you have sex at this time. However, everyone's physical constitution is different, and the safe period is not absolutely safe, so female friends who do not want to get pregnant should not believe too much that they will not get pregnant before menstruation.
