PCOS-TTC

I was told by my OBGYN that I have PCOS. My ob didn't go an ultrasound he just prescribed me metformin to just see if that helps get my period. Well it's been 3 weeks and I go back this tuesday to see if I get my period and if not he's going to try something out I think he didn't tell me much of what he was going to do if I didn't start my period. Anyways, I'm asking for the ladies that have PCOS and are ttc or have conceived what are some things you did to boost your ovulation and egg quality. I've seen one post on here that someone used Myo D-chiro or what ever it's called, has anyone ever used that and helped? Please help me. I'm really desperate to conceive. Since I've been on metformin I've had some side effects and this past Sunday I had really bad cramps that lasted around a minute maybe a minute and 30 seconds. After that didn't have any cramps that bad in my right side which I think was in my ovary area, went into my lower back back on the right side only and into my hip. Then Wednesday I had really light pink spotting and I have no idea what that was. I only baby danced with my husband 2 times this whole month because I'm just trying to get my period back, but after that spotting the one night I haven't had any more spotting or anything. I've been constipated few a few days I'd say since Tuesday. Please give me some insight and advice or tell me what I might be experiencing?
