I had a similar experience with cerazette too.
I have been on the combined pill continuously for menstrual suppression since I was 29 and don't bleed at all, but during COVID I was unable to get my usual pill for over a year in my early 40's as the local family planning clinic I was obtaining it from closed down.
I tried to get a prescription from my GP but they said they had no record of me being on the pill and would only give me cerazette over the phone.
One cerazette daily didn't shut me down either, I continued to have a completely regular 28 day cycle and after a few months of this I ended up taking two daily, which did the trick nicely however I wasn't happy to live long term with the resulting low estrogen levels for health reasons, so as soon as things opened up I went back on a combined pill which I remain on, bleed free, to this day.
