First post for me and i'm panicking :( I have a bicornuate uterus and have just found out that I have gestational diabetes too. According to the midwife my LG is average size for 31 weeks and im 25 weeks. I have really ballooned in the last couple of weeks :( has anyone been thru a pregnancy with both of these conditions? How many weeks were you when you delivered? They're already not going to let me go past 37 weeks as I have a heart condition but surely she's going to run out of room to grow if she's so big and I have the bicornuate? Any of your advice would be really appreciated :)
