Skyla

I'm currently on the pill, but want to switch to a method I don't have to constantly remember and also doesn't contain estrogen. Excess estrogen caused my moms breast cancer that she's battling now, and I already have increased risk due to family genetics (two of my mom's Aunts also had breast cancer). I am considering and IUD, but do not want ParaGard because it typically causes crampier periods according to the internet and my gyno. I got on the pill because of hellish cramps and I refuse to go back to that. I have done some research and I'm leaning towards Skyla. Any thoughts?
