All right. So I started a new birth control around March 31st. I started it late so I took too many. Then on April 14th I had sex without a condom but the guy pulled out. 1-2days later I have menstrual cramps and bloating. Could I be pregnant and know so soon? Or is it just because my birth control hasn't gotten used to my body and is still acting as if it were on my period right now?
