Microgynon 30 pill and lighter periods

I was given this pill when I was 15 and didn't really know any other options for hormonal contraception. I didn't really notice any negatives for the majority of the time - I was on the combined pill for about 9 years altogether and did switch pills towards the end at one point but it's hard to remember why now as it was so long ago. I think it was because I was struggling to lose weight and also had little to no sex drive. I didn't have enough knowledge of hormones and contraception side effects at that time to know if it was my pill or other factors causing these - I wish I knew what I know now about this topic!

Originally went on the contraceptive pill to control and ease very painful and heavy periods, it helped and made my periods regular and easier to deal with. However, around 12 months in I began having regular migraines with aura which are dangerous when using this pill, it was an amazing pill other than that major side effect I had no emotional affect because of it.

General side effects were minimal but had constant spotting that didn't improve over time. Switched to a different pill (Yasmin) and spotting stopped immediately. Switched back to microgynon due to other bad side effects from Yasmin and spotting again within 4 days. Time to continue the search...
