I started taking the noriday pill about a month ago when I was on my period. For the first week I was late in taking it a few times but for the following 3 or so weeks I have taken it at exactly the same time every day. However, I should be getting my period now seeing as it s been a month since my last one, and my period has never been late, seeing as it s normally a week early and I haven t got it yet. I did have unprotected sex about 4 days ago but I didn t think that would be a problem whilst being on the pill and making sure to take it consistently at the same time. Does the noriday pill delay periods or could I be pregnant?
