I Recently Switched Obgn Drs. I Decided To Change After

I recently switched obgn drs. I decided to change after a myomectomy in 2012 and countless IUI and a failed IVF procedures. At the time of the fertility treatments I had many many ultrasounds, also had my tubes x rayed and also the imaging of my uterus with the dye ( forgot the name)

So my new dr ordered an ultra sound because the last time I had one done at the fertility clinic I had a cyst on my overy. The new dr called with results and explained I have a bicortunal uterus. I was never told that before.

In your experience does this often go undiagnosed often? After all the test I have been through and my myomectomy which was surgical with a large incision how could this go undiagnosed all these years. Btw I am 39 years old
