Can you get pregnant if you have sex on the first day of your period?

Whether you can get pregnant by having sex on the first day after your menstrual period depends on how long your menstrual period lasts and how long your menstrual cycle is. If your period is clean on the 8th day of the menstrual cycle, and your menstrual cycle is 25 days, you can get pregnant if you have sex on the first day of your period. However, if the menstrual period is 5 days clean and the cycle is 30 days, it is not easy to get pregnant if you have sex on the first day of cleansing. Since the ovulation period is basically 14 days before the next menstrual period, the time of ovulation will also change accordingly depending on the physiological cycle. Therefore, whether you can get pregnant by having sex on the first day after your period depends on the timing of your period and the length of your menstrual cycle, so that you can tell whether there are any conditions that may lead to pregnancy.

On the first day of the menstrual period, the egg begins to grow and develop. If no perfect egg cell is released, sperm and egg cannot combine, it is not easy to get pregnant. However, sexual intercourse is strictly prohibited during menstruation. During the menstrual period, the uterine wall falls off and is discharged from the body through the cervix and vagina along with the menstrual period. At this time, it is very easy for bacteria to breed during intercourse. Bacteria can cause infection and may cause vaginitis, cervicitis, endometritis, and even pelvic inflammation. Severe cases may cause endometriosis and even secondary infertility. During the menstrual period, you should pay attention to cleanliness and hygiene, change sanitary napkins frequently, and sitz baths and sexual intercourse are strictly prohibited.

The probability of getting pregnant on the first day after the menstrual period ends is relatively low, but it does not mean that it is not easy to get pregnant. Because for women with regular menstrual cycles, the ovulation period is about 14 days before the next menstrual period. From the day when the menstrual period ends to 3 days before the beginning of ovulation, this period is called the safe menstrual period before ovulation. From the first day after the end of ovulation to the day before the next menstrual menstruation, is called the safe menstrual period after ovulation.

Some women use safe period contraception for the sake of convenience, but there is still an abnormal ovulation period caused by changes in mentality. Even though they are in the safe period of menstruation, they may still get pregnant. The failure rate of safe period contraception is as high as 14%-47%. Some women also have random ovulation periods or abnormal ovulation periods caused by endocrine imbalance. Therefore, women who have just finished their menstrual period or have a long menstrual period should avoid using safe period contraception to avoid unwanted pregnancy.
