Just not sure..

Husband and I have been trying for almost 2 years now. Starting seeing my doctor a few months ago. I have very irregular periods. They are few and far between and I've yet to have a positive opk. My bloodwork came back normal and my husband had a sperm analysis. I have an ultrasound next week and a couple weeks after is my follow up on everything before they send us to a fertility specialist. (Just a super long process with tricare) we're just nervous about these test results and what to expect. They thought I have pcos since I have 2 aunts with it but since my bloodwork was normal that they're not sure now. Anyone care to share their story? Anyone in a similar situation?
