Pregnant? Please answer...!!!?

If you are pregnant (which it really seems like you are) you probably got negative results because its only been a short time since, wait a couple more weeks or even a week to take another test. The short periods you had, could be the implantation happening because you only will get that bleeding once like that and then never again for another 9 months. So don't bother to take your pills unless you really know for sure that you are pregnant or not
