Hi doctor
I had unprotected sex on 28th march but my bf didnt cum inside. On 5th when my period was due i got some bleeding for 4 days without any period cramping or pain. Then again i had sex on 12th april and i took plan b on 14th april. Then on 20th april i got my period for 4-5days. I went to doctor on 20th april because i had sex that morning too with condom. She did pregnency test that was negative. Now again on 1 may i got bleeding with very slight lower stomach pain. The bleeding was very dark in begining days. Now its red. What is it?
