I just finished my first pack and started my second pack of birth control (Tri-Sprintec) yesterday , I had unprotected sex yesterday and today ,& I didn't not take the last 7 white (placebo or reminder pills ) I started my first pack on the first day of my period.. Am I safe or in risk of getting pregnant ? I also changed the time to take it from 3:30pm to 10pm on my second pack one more thing I also started my period during the last week ( reminder pills )
