I had a normal 30 day cycle and started my period September 3-7. I started my new birth control pills for the first time September 8. I took my pill everyday on time thru September 15. I missed my pills September 16 thru September 18. September 19 I started medium bleeding that lasted until September 23. I never took another pill but I've been having unprotected sex almost everyday since September 8. Should I expect my period on time like before birth control or start tracking from the bleeding after missing the birth control pills?
