TTC with irregular periods

Hi All. I’m TTC ASAP. 😭 I have irregular periods, I still track but I can go months without a period. I’ve had ultrasounds & testing done which showed up negative for PCOS & endo. I’ve been trying for a while. I’m also fat so the only thing the doctor tells me is to lose weight so they can give me some type of medication for fertility (not <a href="https://glowing.com/glow-fertility-program">IVF</a>). I’m currently looking for a different doctor but I’m the meantime Any idea what the next steps are that I can take?
