Normal menstrual cycle in women is of 28 days. Counting day 1 as the bleeding starts, it is considered to be safe to have intercourse for 1-8 days and then again from the 22nd to the 28th day (till next cycle comes). The ovulation occurs at the 14th day during normal menses in which ovum is released from the ovaries. And, the sperm can live for 2-3 days in the uterus which can fertilize the ovum. Therefore, it is advised to avoid the sex during the ovulation phase. But, it is not the safe and perfect method as many women have variable menses from 26-32 days. So, the ovulation period varies accordingly and one can get pregnant, unknowingly. Always use condom which is one of the best and easy method of contraception.
