Brand new here and doctor thinks I have PCOS, but no symptoms

I'm 36 and TTC. After 5 years of no protection we went to a fertility doctor. He THINKS I have PCOS, even though he can't prove it. I am regular every month, like clock work. I ovulate on my own. I don't have any signs from ultrasound of anything abnormal. Not insulin resistant, or pre diabetic. My blood test results are almost all normal. E2 is low. Doctor recommends <a href="https://glowing.com/glow-fertility-program">IVF</a>, we can't afford it. He said we can try <a href="https://glowing.com/glow-fertility-program">IUI</a>, but it has a 10% success rate taking in to consideration my age (he didn't seem too keen on trying it). I had gastric bypass 3 years 9 months ago and had major complications. I couldn't keep solid foods down for 7-8 months, there was a lot of vomiting in that time, and a LOT of weightloss. One of my test results is off and the doctor asked if I had an eating disorder, I think it's because of that timeframe that my number is off. My understanding is it can be a sign of PCOS or a previous eating disorder. No negative side effects now. I'm a healthy and steady 160-165 lbs. Just really want to grow our family- feeling broken and disappointed in lack of answers from the fertility doctor. Any suggestions?
