Uterus didelphys. Anyone else?

Katrina
So, I apparently haves double uterus. This is causing some space issues with my pregnancy. Now, this is pregnancy number two for me and there was no telling of this with my first(she will be eight when baby is born). 
My main worry is that I'm not going to carry to term. 36wks would be great but reading has lead me to believe that it will be even sooner than that. My daughter's due date was Nov 10th and she came Oct 28th. This baby is due Nov 6th. The doctor suggested the two uteruses are different sizes and my daughter got the one-bedroom aparrment and this baby got the studio. 
Does anyone else have this? What was your experience with previous pregnancies or what has your doctor told you about this one? Thanks, guys!
