Hello I know this is probably a stupid question but here is why I think I could be pregnant. Me and my boyfriend are always fooling around, recently we have been dry humping with me in a thong and him in underwear for 5-10 minutes, no ejaculation at all. Also, when we are laying down , he pulls my pants down so I'm just in my thong and he basically (this is embarrassing) puts his naked penis in between my butt cheeks but not in my butt just rests it there .. For a few minutes. I haven't felt any liquid come from his penis during that either and he said he never ejaculated or pre-ejaculate . IF he did.. Could I be pregnant? My back hurts I have cramps slightly and my period is supposed to be tomorrow - if it doesn't come should I be worried? We have never had sex :/
