I'm a little confused. My Period is 21 days a part from last month when it was 3 days early, but this month if I count 21 days from the 19th I'm 3 days late. Me an my boyfriend use the pull out method, but when we've had sex he's pulls out way before he's even close to cumming, so to be safe I did a test which was negative, two days after my missed Period. I don't know if it's just me stressing or if because my Period was early last month it's going to late, 3 days late as it was 3 days early I dont know what to do, i feel sick even thinking about being pregnant
