Last Friday night (2nd December) me and my boyfriend had unprotected sex - he ejaculated inside me. On the Saturday morning (3rd December) I panicked and realised I hadn't taken my pill on the Friday (I am on the combined pill), I took saturdays pill as normal along with fridays pill which I had missed. I take my pill at 7am every morning. On early hours of Sunday morning I was sick once , and on Sunday afternoon I was sick twice however I had been out drinking so I am hoping this is why I was being sick! On this Sunday (4th December) we had sex however we used a condom. I have just taken my final pill of my pack so should be due a period soon, I usually start my period on a Saturday. I am very worried that I could be pregnant? I just want some reassurance and a second opinion please!
