Feel light headed after taking deep breath’s

Cherry

Why do I get so light headed when I breath in more air while talking? I have shortness of breath and I’m 7w5d w my first. Every time im talking or whispering I have to constantly breath in more air. Sometimes I take fast deep breaths kind of while praying or talking (when I pray I whisper quietly) and I get lightheaded or my stomach starts to feel weird. My chest also starts to hurt.

It feels like someone knocked the air out of me literally and when I take deep breaths I feel like this 🥲. Does taking sudden and fast deep breath’s harm me and my baby? Should I stop doing it?
