Im only 16, i have a amazing boyfriend and well we had sex without a condom and we dont know if he came or not. And its been weeks since then and i should have had my period all ready. So im really late on it. But im getting cramps but nothings happening. And i also havent been very hungery and some things when i eat then make me feel sick. And i also smoke and thats been making me feel like im gonna puke. So i just need to know if i might be. Please and thanks. ?
