Combined pill 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.

I originally went on the Gederal 30/150 combined pill because I had irregular periods and acne. This pill was recommended by my doctor to specifically help with acne. I really liked this pill, I didn’t feel like I experienced any side effects and it really helped clear up my skin. I still got the occasional spot but my skin was so much better. I also liked the ease of being able to chose if/when I got my period by continually taking the pill or having a 7 day break. My periods were super regular and would typically start 2 days after starting the 7 day break, and they would last 5 days with 1-2 heavier days in the middle but mostly very light. I didn’t notice any mood changes. Unfortunately, after about 7 years on this pill I had a few migraines with auras and was told by my GP that I had to stop taking this pill due to the risk of Stroke. I am now on the mini-pill which I am experiencing some negative side effects with.
