So 3 days ago me and my gf had sex and after that I ejaculated outside her lots of semen came out. I ejaculated on a toilet paper (to be more specific). After a few hours I asked her if she felt something hot inside her (besides my penis). She said "yes" she said it's the same feeling like when I accidentally dripped some of my semen on her thighs. We're both scared. Can she be pregnant ? Could I accidentally cummed inside her without me knowing ?
