TTC with PCOS

My husband and I have been ttc for 21 months. I was diagnosed with PCOS (genetic) last August. I’ve been on metformin since. We did an at home sperm test and it showed he was normal, and I ovulate regularly even though I miss 2-3 periods per year. Just feeling discouraged and wanted to exhaust all of our options naturally before we seek a fertility specialist. Is anyone else in a similar situation?

Currently 7DPO, AF expected in 9 days. Still hoping for this month to be it.
