Ovulation occurs on the first day after menstruation

If you have sex on the first day after your period, the chance of pregnancy is relatively small because this period is the safe menstrual period. However, the safe period of menstruation cannot achieve 100% contraceptive effectiveness, so it is not recommended to choose the safe period contraceptive method in clinical medicine because the failure rate is relatively high. Therefore, when symptoms of delayed menstruation occur, early pregnancy testing must be carried out. If the diagnosis is that of pregnancy, a color Doppler ultrasound examination should be performed immediately to rule out the possibility of ectopic pregnancy. However, if there are no fertility requirements, termination of pregnancy surgery can be performed around 49 days of pregnancy.

For women with regular menstruation, the first day after the menstrual period ends is the safe period, and it is not easy to get pregnant during this period. However, for women with a short menstrual cycle or relatively irregular cycle, it is difficult to determine the exact ovulation time. After the menstrual period ends, early ovulation may occur, which may lead to pregnancy. It is recommended to determine whether it is safe based on changes in your own menstrual cycle. If pregnancy is possible, you can use contraceptive pills in time within 72 hours to avoid unmarried pregnancy.

If the menstrual cycle is 23 days, the menstrual period takes 9 days to complete, and ovulation occurs on the first day after the menstrual period ends. If the menstrual cycle is 30 days, ovulation will not occur after the 9th day of the menstrual period. Therefore, it is necessary to judge whether ovulation will occur on the first day after the menstrual period according to the menstrual cycle and the time of menstruation. The menstrual cycle of most women is 28-30 days, and the ovulation period is 14 days before the next menstrual period, so you can know whether you will ovulate based on your own menstrual period. The menstrual period is affected by the natural environment and the mentality. Once the physiological cycle changes, the time of ovulation will also change.

The most important function of the ovaries is to secrete estrogen, which, through the alternation of estrogen and progesterone levels in the body, causes the egg cells to undergo the process of growth, development, and ovulation in the middle of the menstrual cycle. Therefore, the ovulation period begins at the beginning of the menstrual cycle. If there is no fertilization during the ovulation period, the egg will gradually die. After the next menstrual cycle, a new round of egg development will begin again. If you understand the principle, you will know that after the menstrual period is over, the egg cells in the ovaries have already started to grow, and the ovulation period has not arrived until the menstrual period is over, which is basically in the middle of every two menstrual periods. If the menstrual period is a 30-day cycle, the actual ovulation period is about 14-16 days in the menstrual cycle. However, the regularity of ovulation is not relatively fixed, and there are also a few early or delayed ones.
