I had my last period on September 1 and missed the pill on September 11 and 12. I had unprotected sex on September 11. Took 2 pills on September 13. Can I get pregnant?

Just so you are aware... you could still get pregnant even if you didn't miss those pills... the pill isn't 100% effective (the chances are low... but far from nonexistent).

Any time there is penile insertion there is the risk of pregnancy. No form of birth control is 100%. You can reduce the risks, but not eliminate them. So yes, you could be pregnant.

Thanks. I stopped the pill on Wednesday 18 and had an early period so I know am not pregnant.
