Mono-liynah causing extended menstruation?

I’ve been on my period for 16 days. I’ve been taking Mono-liynah continuously for 4 months now, and have never had a period this long. I was taking Junel, but I switched because my periods became super chunky and painful? I’m now having the same issue with mono-liynah, except I’ve had my period for 16 days now. I’m not bleeding heavily, but there’s enough blood that I have to wear a pad.

I think I have PCOS as well, because im pretty sure if I didn’t wax, I’d grow a beard Santa would be jealous of, I cannot lose weight, my periods are super painful, almost nauseatingly so…idk anyone have any advice?
