Mini pill vs Spermicide

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.

Still affected by a bit of acne, but not experiencing mood swings like when I was on Yaz. However, I am having severe break through bleeding every few weeks, and it lasts for 1-2 weeks every time unless I stop taking the pills and let it happen.

I like Slynd except it has caused almost daily headaches. No effect on libido which I always have with estrogen-containing pills, but high is great. But more spotting than normal.
