I started Cerelle mini pill almost 3 months ago and

Patient: I started Cerelle mini pill almost 3 months ago and it has only been within the past 2 weeks when I started having sex again with my new boyfriend. We have been having safe sex using a condom as well as me taking the pill however I am a few days late getting my period. I have never missed a day taking the pill and if I am late taking the pill it would be by an hour or 2 max! My period was normal last month, a lot lighter than usual & lasted much longer than any of my other periods, but I have been told and researched that this certain pill can cause irregular or even missed periods. I’m just slightly worried and wondering is there any chance I could be pregnant even though we used a condom and I’m on the pill? Thanks.
