This is Dr. David. I am reviewing your question now and will be with you momentarily.
what is the "cereals contraceptive pill?"
did you have unprotected sex after you stopped taking the pill?
usually you can take a home urine pregnancy test when you miss your next period or 3-4 weeks after your unprotected sex
you can see your doctor and get blood testing for bHCG sooner than 3-4 weeks to know if you are pregnant or not.
