I would really like to find people in the same boat as me, though 'tis proving rather tricky. I had a fibroid discovered during my lap and dye in December and was told I would need a myomectomy as it was partially blocking my cervix and in a prime place for implantation. Five weeks on, I had a very long ultrasound scan that found ... nothing. Next up MRI scan to try and find the bugger, it was very clear on the lap photos. If I don't find anyone I will keep updating as a source for anyone else in my bizarre predicament to stumble upon. I feel like a bit of a freak of nature. Why would I have an invisible one? Anyhoo, do join in if you have any pearls of wisdom or are facing surgery for removal etc.
