Chartoria

My cycles are regular I had one around October 18, 2022 it was supposed to come on Nov 28, 2022 and supposed to come on a week ago per my app. I went and did a blood test and pregnancy test which came back negative I've never had irregular cycles in my life and I've also never been late 12 weeks with a period, can anyone give me some advice on what I should do?
