My period was all messed up.. I had it Sept. 10th, Sept. 25th, and then on Oct 8th I got something like a period but it was short and light? On Oct. 24th I had sex with a guy but I couldnt stay wet and it was just all bad so we stopped and he couldnt finish or anything.. so it seemed more than pointless and plus he was so small the condom had trouble staying on (not to sound mean or anything!). On the 26th and 28th, my ex and I had sex and I told him to not come in me... but he did. On the 30th I had cramping and on November 5th I bled after intercourse and the next day what seemed to be implantation bleeding. I had a positive pregnancy test 6 days later. I went to the ER to see if everything was okay because I was in a lot of pain and they said i was 5 weeks 6 days and that was November 25th. They said my acclaimed period was 6 weeks 6 days ago.. I've done conception date calculators and all and it says 'conception date October 28th' does that mean the 26th when he came in me or the 28th that I got pregnant? HELP!
