Hard time breathing

Brittney • Mommy of 2. #Son&Daughter
Does anyone else feel like they have a hard time breathing/ shortness of breath when they are lying flat on their backs? Or at other times. . (I mainly feel like this when I'm laying down) I'm almost 24 weeks, and I'm still pretty small but I just find myself having shortness of breath all the time now and I don't remember having this during my last pregnancy.
