Microgynon 30 pill and weight gaining

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!

Was on combined pill from around age 16 to 19 with no major issues apart from a bit of weight gain (and bigger boobs) ,until I became very depressed which seemed to clear up when I came off the pill. Difficult to say if it was the cause. Had a break for a while and then tried taking the combined pill again around age 24. Unfortunately this time it made me very sick for the first few days every month to the point of vomiting multiple times. I switched to the progesterone only pill and have never looked back!

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.
