Hey just need some help. My boyfriend and I dryhumped, he didn't come and I don't think he pre comed but I'm just taking precautions. I gave him a hand job too but I know sperms die within a couple of minutes when it's in the air. I got my period two days later. There didn't seem to be anything different about it, lasted about 5 days. I ament due my period yet but I just want to make sure. I'm a little paranoid and stressed so I'm afraid that'll delay my period. Would love some help thank you:)
