PCOS and round one clomid

Sarah
Hey all!! 
So my hubby and I have one daughter that is two and a half. She was a surprise, seeing as I was on birth control when we found out We were expecting.
Now we're trying to grow our family some more, and have been for over a year.
I've had PCOS since at least 7th grade, and that's why my doctor believes I got pregnant on bc.
I had an ultrasound yesterday and I'm not ovulating at all.
So I was put on 50 mg clomid.
Obviously clomid doesn't make you pregnant, it only (hopefully) makes you ovulate.
But is there any thing I can do to help myself make the most of it?
I have preseed and OPKs.
But any food, supplements, nutrition, position, wives tails, anything?!
