Any advice would help.

Idk where to start. My periods have never been regular only when I was on the pill. More than two years ago I got off of the pill and everything seem normal. Then I only started getting my periods once every three months. I got scared and when to see an OBGYN. I was diagnosed with PCOS. Now my hubby and I are trying to have a baby, she put me on Clomid, it worked the first round but we lost the baby at 6 weeks. No I'm having a hard time because Idk when I ovulate, I have to just wait for my periods and I feel like I'm just in the dark with everything.
