Discouraged & Confused

We have been ttc for 18 months. I have always had consistent cycles until June. I went 2 months with nothing. I thought for sure we had done it but my hpt were all negative. Dr ran blood test and still negative. She also ran a ton of hormone blood work to check for pcos, thyroid problems ect. Nothing! Everything is normal. I finally had my period in August. Now I'm a week late all negative hpt. I am not ovulating for some reason.

We want to adopt but it is soo expensive! I honestly would have adopted before even trying natural but we didn't have the extra money..

My insurance will cover 3 <a href="https://glowing.com/glow-fertility-program">IUI</a> cycles.

Fertility or Adoption. How do we decide our next step!?
