I'm 18wks 19 tomorrow with my 3rd. I've been having a lot of pressure I'm at the bottom of my lungs. It feels like when the baby is bigger. When I'm doing things I have to take breaks to sit and catch my breath because it takes my breath away. My heart will start raising too. It helps the most wgen I lay on my left side. I know this is normal in late pregnancy but this early? It's making my day to day very difficult
