abnormal uterine bleeding
"I've been taking Sprintec for years - when I lost my health insurance, it was cheap, and was a mono-phase pill that I could take continuously, and it's been the best pill I've tried for cramps and lighter/shorter periods.

I use it to control my polycystic ovarian syndrome (it's a low-androgen pill that helps control my PCOS-raised testosterone levels). If it impacts T levels too far it can lower the sex drive too much for some people - for me, it removed the worst aspects of having naturally high T-levels and put me into 'normal' range though. Including "balancing" my sex drive and clearing up my acne.

I also use this pill continuously (4 period/year) to minimize pre-menstrual and menstrual migraines - "yay" I get both types. No period=no hormonal migraines."
