When to call a doctor?

Hello

I was on birth control for 9 years and stopped taking the pill mid June after the placebo week. I got a period (which I assume is a withdrawal bleed) 4 weeks after. My next cycle was 65 days, and I’m now entering day 73 of my current cycle. My husband and I started actively TTC’ing mid November. I don’t know the last time I’ve ovulated. I know it can take up to 6 months for my body to adjust, but that 6 month mark is approaching and I’m feeling pretty down and concerned. Has this happened to anyone else? When is a good time to call my doctor?

Thanks,

Deven
