Hello, I am a 17 year old virgin and last night I grinded on my boyfriend nude in the pool and I just recently had my period 2 days before (Last night was a friday, my period ended on that wednesday). He did not ejaculate at all near me or inside me, there was no penetration at all. I just am very worried of any possibility of a pregnancy and are seeking help in whether I should take a morning after pill because I don't take any birth control and I just need to ease my mind.
