I have pcos and I got pregnant using clomid, however my husband has morphology issues so we worked with a fertility specialist. Most women with pcos and no male factor issues can get pregnant with just clomid. There are other medications if clomid doesn't work. As for miscarriage you can take progesterone suppositories to help deter it. That's what I did for the first trimester and we had a healthy baby! Good luck!
