Junel to Slynd

After a long time of pain and breakthrough bleeding on Junel 1.5/30, I am switching to Slynd per the advice of my gyno. I had a transvaginal ultrasound for pelvic pain that showed up clear, so my next step is changing my pills.

Experiences switching from a combo pill to Slynd? Any weird symptoms I should watch out for during the 3 month adjustment period?
