Trying to conceive and have PCOS

I have PCOS. Got my period at age 11, started gaining weight threw out the years. Noticing period not showing up for months at a time. I had a ultra sound done no signs of cysts. Blood test all came back good. I ovulate. Just irregular and excessive hair growth (unfortunately). Me and my husband are trying to conceive, it's been 6 months so far nothing.

This is my second month on Provera. Forced period normal last month.

Question is ...

1. Any tips on conceiving? (Lubes, vitamins??)

2. If I do become pregnant what kind of complications can become with having PCOS?
