I think I was misdiagnosed. Help!


I need some help. About 3 years ago I was diagnosed with PCOS by my OBGYN. In November 2018 I started seeing a fertility specialist bc we were ready to conceive. After my first 4 months he told me that I didn’t have PCOS and he couldn’t figure out why my regular OBGYN had diagnosed me with it. He showed me all of my bloodwork and everything looked normal and after the first 4 months of ultrasound there were no signs of PCOS on my ovaries. Well, fast forward to today. I went in for routine visit on CD 11. We are going to do an <a href="https://glowing.com/glow-fertility-program">IUI</a> on Monday. So, he did my usual ultrasound and diagnosed me with endometriosis today. He says I have an endometrioma (sp?) on my ovary. It’s 3mm in size. My question is... how would he not have seen that in the previous 28 ultrasounds he has done? I’m thinking it may not be a correct diagnosis... I have zero pain. Periods are normal. Sex isn’t painful. Would this have shown in previous ultrasounds. He has literally done 4 ultrasounds a month since November.
