I'm 17 years old, I had my implant took out that I had in for 3 years, then came on my period the next day. This was 37 days ago. Usually on the implant I never really tracked my periods, they were irregular so I'd forget to do it. I had unprotected sex 2 weeks ago& now I have sore breasts, white discharge and light period cramping. Could I be pregnant or just due on my period?
