Just me. I am 28 years old. This is my 2nd child. They will be 10 years apart.

Going to doctor tomorrow, so will ask him then. But just wondering if anyone else has had any issues with being able to catch their breath? There are times when I have to sit and take deep breaths to feel like I am getting enough air. It happens at random times of day and while I am doing different tasks, anything from laying down to working or housework. It seems it happens more when laying down though. Could be just baby pressing on something, idk. But Im not even that big yet, im just 27 weeks. Am I completely weird, or is this normal for some moms?
