OP, I am very sorry to hear about your recent diagnosis. During my second round of IVF, my Shady Grove doctor said as we were about to do the transfer, "Did you know that you have adenomyosis?"
I was of course completely panicked, especially after I got home and consulted Dr. Google.
I did end up with a pregnancy, but it unfortunately did not end well. Around 24 weeks, my daughter had no heartbeat, and I delivered a still born baby after a horrendous night.
Now, no one has ever said that there was a direct correlation between the two, but I was so far along and this is the likeliest explanation.
I'm sending you big hugs.
