Mini pill and lighter periods

i have had really bad headaches on this pill, and i never had headache before taking it. i have also had a large amount of bleeding, i bled for 11 days 2 weeks into taking my first pack and I also had lost part of my uterine lining at the begging of those 11 days. since then i have had spotting which i also have never had before. i am considering taking a new pill but i don't know which one yet.

Worked fine for many years and helped with having much lighter, shorter periods with less cramps, but after briefly switching to the shot and then switching back to the pill I have been having breakthrough bleeding every other week for months now and my periods are no longer lighter or shorter so I'm trialing a different type now.

I am on Slynd for heavy period and clotting. It stopped the heaviness and clotting. I do have some dryness in my mouth and apparently my vagina. It may have contributed to acne but not sure.
