Ttc without a period

L

We’re trying to have our first baby but I haven’t had a period in 7 months so it’s making things so hard. Last month I spotted for the first time in 7 month for 2 days but that’s about it. We basically have been trying blindly. I finally got referred to a fertility specialist by my doctor but my appointment isnt until January 15th. I figured I try ovulation tests but I literally don’t have a cycle so I’m confused on how to go about it. Any tips? Anybody else ttc without having a period? I feel hopeless and alone in this journey.😞 Any stories or help is highly appreciated
