I too had bad side effects from BC and had heavy bleeding & cramping since puberty (nexplanon = bled for 4 years straight, nuvaring = the hormones gave me migraines with auras, depoprovera = migraines with aura but from the progesterone hormone this time.) My sensitivity to gynogen hormones wiped out 90% of BC medications & my heavy bleeding made me desperate to avoid periods all together. As far as supplements, I took a fenugreek blend called Alpha-King from GNC. I didn't notice any difference in bleeding but my energy was peak and I did notice less belly volume without changing my routine. (I think it's because I had more energy and that lead to more activity naturally.) In the end, I ended up going for sterilization via hysterectomy. (we still have periods with tubal ligation) The recovery was difficult but the pay off was magnificent. Good luck!
