Hi Dr. I HAD SEX 4days after my period. We didnt use control. Is there possibility of pregnancy?

Possible. It is possible that you could get pregnant but not that likely. You usually ovulate 12-14 days after the first day of your period. Having sex within 4-5 days before or after ovulation can result in pregnancy. If you miss a period check a pregnancy test. Consider using a form of contraception if you do not want a pregnancy.
