Ok, almst 6 weeks ago, i had a mishap and the condom broke. So obviously v. paranoid, i did quite a few tests.....4!! All negative. I then got my period, but i know a few of my friends have been preg. and still had their period. So.....i did ANOTHER test yesterday, again negative. BUT i am 6 days into my new pill packet and i have really bad stomach cramps and back ache and i am feeling really tired, could i still be preg???
