Patient's question:
Can sexual activity over the past three or five days cause pregnancy?Doctor's answer:
The menstrual period of a girl is generally 28-30 days, but some may not have a period until 35 days or more have passed. Therefore, it is necessary to state one's menstrual cycle to calculate the safe period and ovulation period. Just remember to count from the first day of the period: the first 7 days are the safe period, and the 8 days after the period ends are also the safe period. Except for the menstrual period and the safe periods before and after the period, all other times are the ovulation period. Also: the safe period after the menstrual period is safer than the safe period before the menstrual period. It is best to buy a calendar, record the last menstrual period to predict the next one, and then use different colored pens to mark according to the method taught above, dividing the next month's safe period, ovulation period, and menstrual period.
