I am on my third pack of Yaz combined contraceptive pill. It consists of 24 active pills and 4 inactive pills. I have never missed a pill. I had unprotected sex on Wednesday night, drank my pill on Thursday evening and forgot my pill on Friday. The pill I was meant to take on Friday is the last active pill before the inactive pills. I only realised on Sunday and drank the pill I was meant to drink on Friday, exactly 48 hours after I should have. I didn't drink any pills Saturday or Sunday since those days are inactive pill days. I was also meant to get my period on the Sunday but didn't. Could I be pregnant? I have been under a lot of stress lately and I know that could cause a late period. I also read that I have to start with the next set of active pills the next day (Monday) even though I would normally only start on the Wednesday since I missed a pill in the last week of active pills.
