I'm on my second month of birth control and I'm on the placebo week. I started my period on the 4th day of the placebo pills. My boyfriend and I had unprotected sex today which is the fourth day of my period And had a condom slip. I I've taken all the active pills on time give or take 5-10mins Haven't Missed any days. Should i consider taking plan b or is the birth control that i am taking protecting me. The birth control i am taking is repclipsen.
