Rigevidon and more regular periods

I was prescribed this pill mainly for my moods and it really did help. I was taking the pill for many years and every month when I had my break in tablets I would get a headache. I thought it was a symptom of PMS but after having a pill review with my GP they advised me to stop taking it. Since I stopped I haven’t had one headache which is quite worrying. They always ask about migraines in the questionnaire but never headaches so it didn’t even occur to me that it might be the pill causing this

Started off on this pill, I'm one of those lucky people who are never sick but while on this pill I would quite regularly feel nauseous a few hours after taking it and on about 5 occasions would vomit aswell, which for me was very unusual but after switching to a different pill these side effects went away.

To be honest I’ve been on this before, but I took packets back to back so I wouldn’t get a period which worked, but now months later I’ve started it again, because my cycle was irregular from August due to plan b usage, and I now bleed on my pill free break, it gives me a sense of reassurance I’m not sexually active anyways it’s been like that for a month now, but atleast I know my cycle is more regular, only thing I would say is around day 4 of me being on the pill free break aka my first day of bleeding I experienced cramps and very bad breast pain PMS syndromes but it went down and it went from heavy bleeding to light bleeding.
