Hi I just got off the pill February 25-26 had my period 2 days and then had sex that Sunday and the fallowing had sex with my boyfriend again Wednesday 6 and then yesterday the 12 . I've had implantation bleeding 9,10 and ended the 11, that came light and became heavier. it was a radish brown color. I went to my doctor And she checked and my test can't back negative everyone tells me it's to early to check. I've had head aches hot flashes bloating moodiness nausea  esexcessive smell and tiredness even my jeans are to tight I've taken the test but still negitive. Can I still become pregnant? Even after I stopped taking my birth control.? I would love to have a baby with my boyfriend.
