Femcon?: You will ovulate after our next period if you aren't taking any birth control pills such as femcon. Period should begin within a few days of stopping the pill.

Femilon OCP: You are most fertile about 2-3 weeks after finishing the 21 day treatment. I would expect you to start a period within 1 week after finishing you treatment. Then another in about 4 weeks.
