Finished the 21 active pills and didn't take the 7 remaining placebo pills and had my period during the 7 days. (April 30- May 6) Started a new pack may 7 (pill day 1) and had unprotected sex may 8 (pill day 2) he came inside me a little bit. I'm scared am i pregnant? Should i take an ECP or continue taking birth control the next days?
