hi. me and my boyfriend were fooling around when he was at my house. He took of his pants and so did i. He put his penis in like 3 times but they were very short. He didn't ejaculate, of that im sure. i honestly dont know if he had pre cum or not, because I was wet when he did. Im late more than 2 months on my period but i do have irregular periods. I have no symptoms so far...should i take a pregnancy test? i am 18 so i can buy one without my mom knowing, but should i? please. any info would be very appreciated. me and my boyfriend have done some research ourselves but we just wanna be positive.
