Is the second day sex that menstruation finished able to be pregnant

After menstruation, if sex occurs on the second day, it is not absolutely safe, because women's ovulation time is difficult to completely determine. It is directly related to women's menstrual cycle, and it is easy to show ovulation before the cycle is short. After menstruation is clean, there is a possibility of pregnancy. Even if the cycle is normal, it cannot completely rule out the possibility of occasional ovulation in advance, so for women who do not want to be pregnant, safety measures should be taken at any time to play an effective contraceptive. For sex without safety measures, it can only be said that there is a chance of pregnancy. If you do not do safety measures and do not want to take medicine indiscriminately, you can also immediately go to the hospital to do B ultrasound to determine whether ovarian follicles are close to maturity, and then make further diagnosis.
