Is it possible to get pregnant before your period?

Patient's question:

No

Doctor's answer:

If your menstrual cycle is very regular, it should be absolutely safe 3 days before your period, and you won't get pregnant if you have sex during this time. The safe period is from 7 days before your period to 8 days after.
The calculation method for the safe period is as follows: First, determine the date of your next menstrual period, then calculate the ovulation date, and finally determine the safe period. For a woman with a very regular menstrual cycle, it is easy to calculate the date of her next period. The ovulation date is 14 days before the next menstrual period, but ovulation is also considered normal within 2 days before or after this date (14 ± 2).
