A few days, maybe a week after having sex for the first time, when i was 14...i got my period, amd i knew it was my period because it was the correct time in my cycle. But my period was super heavy for two days then stopped after the second day. Normally my periods are 5-7 days with heavy flow the first 2 days then it slows down till it stops. I thought it could have been the first sign of pregnancy but then after taking a test and it coming up negative i was clueless. Now 10 months later i know i was never pregnant and im still wondering. My periods are back to normal, but what was that weird period?
