me and my fiance had sex twice. i'm on birth control and we used a condom both times. one time was march 25th, and the other was april 18. i've been really scared that i might be pregnant, so i went and got a pregnancy test at my local health department exactly a week ago (monday). i had my period twice, but it's only lasted for 2 days, but it was really heavy. i'm supposed to get my next period in a week and 2 days. the pregnancy test was negative. i've always been pretty paranoid about everything that goes on. so do you think the pregnancy test was right?? that i'm not pregnant?
