I had a biopolar sterlization done in 1997 and I had unprotected sex a few days before my period I had cramps but no bleeding could I be pregnant
Highly unlikey- bipolar is the burning correct? If so I would say I wouldn't give it another thought- You could take a test to be sure but most likely your period is just late or skipped for some other reason..
PLUS- a few days before your period is not normally a "fertile" time
