Pcos & myo d chiro inositol

So after finding out I had pcos my doctor recommended myo inositol along with berberine and I think something else. Well I start my myo inositol about 2 weeks ago and my period won’t stop. I usually have it for 7 days at most and I’m on literal day 10 of my period. It’s not stopping. I’m not cramping or anything like that but is this normal. Why is something that supposed to be helping just making things worse. Like am I ever going to be able to regulate my hormones. Now I feel like this is just a waste of my time. It’s hard enough remembering to take 4 pills everyday.
