Help!

Brittany

So guys i need some help. I’ve been ttc on and off for the last two years. Last month we decided to start trying again. A friend of mine who has pcos (i do also) and just had twin boys recommended a cocktail that got her pregnant. It consisted of CoQ10, baby aspirin, DHEA, Premama powder, metformin, & conception prenatal. I’ve been taking them all for the past month. Used OPK sticks until i ovulated then had sex just about everyday during that period. Well i didn’t get pregnant.. period arrived.. I’m normally on my period 3 maybe 4 days at most but I’ve been bleeding for now 7 days. I’ve never bled for 7 days. Can someone tell me what possibly may be going on?
