DRUNK SEX WITHOUT A CONDOM

this month, me and my boyfriend got drunk in a friend's party. i was at the second day of my period. he penetrated me but it was hurting him (we were REALLY drunk), so this lasted about 1 minute.

three days after my period ended, we had sex using a condom and we tested it to make sure that hadn't ripped, and it was all okay. but i'm a paranoid and want to know if i can be pregnant or not.

p.s.: i went to the beach two days this week (some people say that the ocean estimulate the menstruation to come) but my period is one day late yet.
