I've been dating someone for four months and we have unprotected sex frequently. He said there's never been a time where he'd be concerned that I would get pregnant and I feel the same way. He has never came inside of me. I had my period last month around the 8th and now I'm a day late. At the beginning of this week I had severe cramps that were more of a stomach pain and somewhat nauseating which is normal for me, but after that day or two it happened, it stopped, and I haven't started my period. I'm nervous and wondering if I should be stressing as badly as I am or if I'm stressing so badly that my period will be a couple weeks late.
