Heart Shaped uterus??

Shannon
Prior to becoming pregnant I knew I had a heart shaped (bicarnate) uterus. The doctor at first didn't really seem concerned, but she is just monitoring closely with more ultrasounds. She is also concerned that there may be a uterine septum. 
Does anyone else have this problem? If so, what has your experience been? 
I am 11weeks and 4days. I feel like everything is growing appropriately, but still worry of course.
