i missed a few birth control pills, but took two each day for 3 days, until i went back to the same rutine. On that week i missed the pills i did not have sex, but the week before i did. A week later after taking all those pills, i think i got my period (3 weeks early) .. what can my period mean? was it even a period, it started with spotting but then it would be a normal light period. can i be pregnant ig i got my period 3 weeks early.
