so around just over a month ago I had dry sex with someone, i remember I was really light on my period whilst doing it, but we both had jeans and underwear on and I had a panty liner on. So I asked him if he cummed and he says he honestly doesn't know? But now it's a month later and I still have started my period!? I think my belly might be a bit bloated... But the time I was supposed to have my period I was ill, like I was weak my head hurt, I was dizzy all the time and I was off school for a few days, could this be why my period hasn't come? And can I be pregnant!?!?! Please help I'm so worried
