I'm talking contraceptive pill and i jump one month without seeing my periods is it possible that i may be pregnant?

Maybe. Maybe not.: Using birth control methods is a full-time job. Once in a while, pregnancy happens even when one uses birth control very correctly. A urine pregnancy test gives a reliable result if done correctly. One can test about 3 weeks after sex (3 weeks after when conception might have occurred), or 1 week after missing a withdrawal period. Tests are inexpensive and sold in stores everywhere.
