I'm on the pill (Microgestin 1/20) and this is I believe my 4th and 5th pack. I've taken it on time and daily as I should (unless it's the 7 day break from the pill at the end of the pack) for the past few months. However, on the 19th of December I completely missed taking my pill but I doubled up the next day and went back to taking it as normal. Then, on the 24th and 25th, I had unprotected sex but he did pull out before ejaculating. I had unprotected sex again on the 1st of January (and once again, he pulled out) and then had my period, which lasted from the end of the 1st (after I had sex) and through the 7th. It was on the 6th that I started to take the pill again. Yesterday, while still on the pill, I started this second period and I've been cramping (which isn't unusual) and the menstrual blood has been a dark brown, which was what it started off looking like during my last period. My question is, is there a possibility that I can be pregnant?
