Is the fertilization is possible on first day after periods?
Can pregnancy occur if intercourse happens during menstruation?
It's unlikely, but not impossible. Sperm can survive inside the female reproductive system for up to five days, so if you have a short menstrual cycle and ovulate soon after your period ends, it's possible to get pregnant from intercourse during your period. However, the chances are much lower during this time of the month.
