TTC, no period for 2 months, neg tests...😞

Hi ladies, my fiancé and I are new to TTC and I know everyone has their journey but I’m 22 and we’ve been having unprotected sex for the past two months with no luck on a positive...and it’s making me rather emotional...

I haven’t had my period for 2 months and I’m afraid that maybe it has something to do with my ovaries? I have always been regular with a 35 day cycle for the past 3 years (35 is normal for me) but I’m 66 days late all of a sudden yet all my tests are negative.

I’ll add that I do have PCOS and have never taken birth control before, I weigh 165 and live a healthy lifestyle. I would go to an OBGYN but I currently don’t have health coverage as I have just moved to a new state.

May anyone give me advice as to what to do or what steps to take...could this just be PCOS or some other underlying cause?
