What to expect for fertility consult?

Kristin
Hello ladies! I'm 33 and TTC #1, I went off bc in February when we got married. My cycles have been irregular since then, I'm only getting a period every 5-8 weeks. I have an appointment on Monday with my OB for a fertility consult (she is not a specialist). I am wondering what I should expect at that visit? Bloodwork at a minimum? I was tracking everything religiously in Glow for about 5 months, but the last few weeks I've felt so discouraged that I just quit tracking and using the app all together. I haven't had a period since August 1 (taken two pregnancy tests- BFN each time). Any insight into what to expect for this first visit would be helpful. Thanks!
