PCOS struggles...

Fellow Pcos suffers. who out there is CONSTANTLY on their period?! I'm on it 24/7 like it'll get really light and I will think yay its gonna stop then suddenly for lack of a better term the flood gates open. Its emotionally and physically so so draining. ive been to the dr and they just tell me to lose weight(which ive been working on I'm down 15 lbs yay) and it should stop or they recommend BC which in turn causes weight gain. Any tips or how do you deal with it?!
