So the past 2 months, i've been getting my period exactly on the 22nd. When I'm stressed, i know it can delay. My boyfriend and I were pretty much dry humping, but he had boxers and jeans on, and i had my underwear (it was lace, and i'm afraid that maybe stuff can get through easier) and pantie liner on, although at times i felt like my pantie liner wasn't in place right, but just around the clitoris area. He did ejaculate, but like i said, he had his jeans and boxers on, and i had lace underwear. Is there any way that sperm can somehow get through? Plus, he didn't ejaculate directly into my vagina area since i was just rubbing against him andi was wearing underwear and a liner.It's past the 22nd, but sometimes my period isn't always exact of course, but i've been pretty paranoid. I've been very active with school, and not getting good sleep and afraid that maybe i've been overactive to where my body can't keep up. I recently got a cold and wondering if that can affect my period in some way. Although lately, I haven't been that nervous about it until now. My discharge has been kind of heavy, whiteish and yellowish. This only started about more than a week ago. My boyfriend and I did dry heaving on the 17th. I've been having a little cramping. I'm worried about being pregnant or something. please tell me advice.
