I had unprotected (my partner finished during oral sex and we had vaginal sex without a condom right after) on Friday and took Plan B on Saturday. I haven't been on the pill for a few months because I wasn't dating anyone but recently starting seeing the person I'm seeing now. I'm just about to start my period so I don't believe I was ovulating when we had sex but I took emergency contraception to be extra careful. I then called my OB and refilled my birth control prescription since I've been off of it for a few months. Should I start the pill right away? Or wait until my period shows up? This is not the first time I've had to take Plan B and I'm a little embarrassed that I had to take it again. I understand that the entire process of becoming pregnant can happen between 5ish days and two weeks, and know that a person doesn't become pregnant immediately after unprotected sex, but I decided to take EC anyway. Thanks in advance!
