Bleeding and BC

I’ve been on Junel 30mcg for 6 months now and it seems like i always spot during week 2 of the pill and during my “break” week i don’t really bleed but just have uterine lining coming out. I’m just wondering if it is normal and whether the Junel pill and dosage is right for me body for this to happen? I’m not that sexually active so pregnancy is not a factor. Any advice or thoughts?
