ok so i had sex with my bf(at the time) on the 4th-5th of july (the day and night of my ovulation) with no condom... i didnt think much of it though. that month about a week later i got my period but it was different then before, at first it was light then it got a little heavyer then it stop, so i thought nothing of it, i have a really flat tummy for some time now and it has never had that much fat on it, and now it looks like i'm 9 weeks prego, i had my "period" two other times, the second one was late by three days and i have never had a late period and it would always go for 7-8 days, but this one only went for 5 days then stoped and started the same way my last one did, the last one started off heavy and barly any clots then it started to slow down the third day then almost stopped but began to start mild bleeding, i have taken 2 hpt and they both came up nagitive, but i have had all the symptoms of being pregnant and every thing so i dont really know if i could still be pregnant.. can any one help me???
