What more can I do to get pregnant?

I have endometriosis. We have been TTC for 3 years but when I had so much trouble I found out I also have PCOS. I am getting on Metformin again startin Tuesday but I also want to ask for Clomid (I really want a baby). Is this safe? Also, what else can I do? I am taking prenatal vitamins, working out, eating right, and of course "working" on it. Is there anything else I could do? I want a baby! I need baby dust too.
