Congratulations on your pregnancy!
I had no idea I had a BU until I had a caesarean. DS was in my left side and was born at 39 weeks but he was breech (due to the BU). There were no other complications during my pregnancy, and I am thankful I didn't know as I am sure I would have worried for the entire pg.
It did take us almost 4 years to conceive so I assume the BU may have had something to do with that.

All the best for the remainder of your pregnancy
