I'm starting to lose hope with my ridiculously long cycle...

My husband and I have been trying for 6 months, but my cycles have been extremely irregular. Since I stopped taking my birth control, my cycles have been 30+ days, 40+ days, and now AF started today after cd 47. I keep getting positive ovulation tests at two different times during my cycle and my bbt is all over the place. I feel like because my cycles are so long, I'm losing more time to ttc. I'm going to make a doctor's appointment to figure out what's going on, but I'm concerned that they'll either say to give it more time or that something is horribly wrong with me. I wouldn't normally post anything about this, but I'm so sad about AF starting and now my husband is getting panicky about it and it's making me worry...

Has anyone had a similar situation, and was the doctor able to help you regulate your cycle or figure out what's going on? 🙁
