So me and my boyfriend were having sex and he wasn’t able to stay hard in the condom. Eventually we took it off and did other stuff that wasn’t penetration. After giving him head for a little bit he went back inside of me. He didn’t cum but there was a small amount of precum or liquid that was coming out of him. Is there a chance that this could cause pregnancy. He was in me for a minute or two u protected. Even after all of that he still didn’t cum. Help!! What are my chances ( I am not fertile- 5 days till period +not on BC)
