Microgynon 30 pill and tender breasts

I was having very irregular, heavy, long periods to the point I became aneamic. This really helped bring it under control, it was great at first. With time I noticed I didn’t feel like myself, I couldn’t experience happiness like normal, I had put on weight, I was getting gut issues like reflux and sensitivity, my hair had thinned, my libido was gone and I was dry even when aroused. I stopped the pill and all these issues fixed themselves after about 6 months but now my periods are irregular again.

Painful sex painful vagina, pain when peeing, constipation, no sex drive, low mood, achey legs, insomnia, generally felt rubbish

I started Microgynon30 becase my previous mini-pill (Cerelle) made me bleed every other week. Pharmacist advised the combined would regulate the periods. Unfortunately within 24h of starting Microgynon30 I have severely painful breasts, swollen and itchy (I went up a full cup size and it's not fun, I can't fit into my bras and running has become impossible). Nipples are itchy and sensitive and get scabby and dry. I have sore muscles as if I was constantly PMSing. The worst side effect though has been migraines with aura. Never had migraines in my life before, and now I do. I'm gonna switch to Slynd now, I don't ever wanna go back on a combined pill ever again.
