Okay I just got off my period yesterday and I had unprotected sex last night and took the plan b one step pill this morning and then about two hours later had unprotected sex again. What would be the chances of me getting pregnant? Will the pill still be in affect and work with the second unprotected sex? I know that the pill isn't a 100% effective but I just wanna know if it's possible that it will not work being that I had sex again & if not should I take the pill again ?
