I am taking Microgynon 30 (21 day pill pack) and I missed a pill on the last week of my first pack then only realised when it was time to take it the next day so I took 2 at the same time to make up for the missed one. However I also somehow finished the pack a day early (probably due to a mix up in time differences from travelling) and had unprotected sex a day before my last pill was taken. Then I proceeded on taking my 7 day pill break and had my withdrawal bleed and started my next pack of pills a day early as I finished the first one a day early. I'm really worried now, is it possible that I could still get pregnant?
