I am 29 weeks pregnant with twins (two girls) and I have been having issues with catching my breath. For example, I was just sitting in the computer chair and I was having trouble breathing. Twin A is low while Twin B is up at the top of my uterus. (just for reference). So what I did was come and laid down and a few minutes later, i felt better. Last night i had to do the same thing. Is it something I should tell the doctor on monday. I dont go back to them until October 8th but the Fetal doctor October 7th. I am concerned but not sure what else to do.
