What is the chance of getting pregnant 1 or 3 days after my period? He ejaculated in me twice 1 day after my period & once on the 3rd after my period

Depends on... It partly depends on when a woman ovulates. If no ovulation 0-5 days after ejaculation, then the sperm have no egg to fertilize. That means it partly depends on one's cycle length, because a woman with short cycles will ovulate closer to the end of her period, but a woman with long cycles will ovulate farther from the end of her period. So, one has to figure out... when does this woman ovulate?
