two uteruses.. anyone else?

J
I am just about 5 weeks along and just found out I have two uteruses from my first vaginal ultrasound last night. My doctor said the only concern might be a premature labor but other than that it's fine. Of course I googled my heart away this morning and cried from reading all of the rare cases but I should have stopped and listened to him when he said that I'll be fine.  Just looking for some support. Did this happen to any of you?
