Hey, I have been on the pill (yasmin) for about 7 months now. After my period I start my new pills on a Sunday. On Saturday, I had unprotected sex with my boyfriend and he pulled out. I was not able to take my pill Sunday night because the pharmacy was closed (I obviously need to think about getting them in advance but I've been busy) I got the pills the next day and took two that day. Is there a high chance that I may become pregnant because I missed the first pill right after my period?
