I started a new birth control. the last 2 month's my period has came when i take the period pills. this month it didn't com. could i be pregnant?

Doubtful: however, no form of birth control is 100% effective. Keep taking your pills exactly as prescribed.

Unlikely: It is always possible that u r pregnant if u have missed pills or taken them late or have taken a medication that interferes with the action of the pill.No method of contraception is 100% effective.However, the most likely explanation is the low estrogen dose in most pills used today.This stimulates so little growth of the lining, missing periods occasionally is common. Do a test to know 4 sure
