My last "regular" period started Sunday March 2nd. I started a new pack of pills on Thursday March 6th and took them right up until Thursday March 20th, then missed the rest of the pills. I started my period on Sunday March 23rd and finished on Thursday, March 27th. I started a new pack of pills on Sunday March 30th and haven't missed a pill since. I had sex on the 20th (last day I took previous pack of pills), then again every day from March 23 until today. Is there a chance I could be pregnant?
