On May 9th I had unprotected sex, it lasted about 3-5 minutes and he didn't finish inside of me because I pushed him off but I am a nervous WRECK.

I've taken about six pregnancy tests so far, just out of sheer paranoia. I haven't gotten my period yet but it's pretty irregular so that's hard to gauge. The last time I had my period was I think the end of March. I just took the E.PT. test this morning, I didn't use my first morning urine though *damn* but I didn't drink anything and I went again and used that. The line is still telling me not pregnant, every response has been not pregnant. It's been about 22 days since it happened and i'm heading to the doctors tomorrow for a blood test.

The only 'symptom' I guess i've been getting is that since around May 16th I get this light cramping like i'm about to get my period but I never did. However i've been horribly stressed over this so that could be pushing my period back.

I know i'm making a big deal about this but I just can't shake the dread. :-( Should I be worried?
