elephant on the chest !!!

Le
I am currently 18 weeks pregnant with a baby boy 💙. But every morning I wake up trying to get a full breath. It's like I have an elephant on my chest . Ive never had asthma or any problems until I got pregnant and it's mostly In the mornings . It's like I have to work extra hard to get a full breath and if I get worked up I can get light headed and not feel well. I have to sit down every little bit and take breaks from whatever I'm doing to regulate breathing . One I sit down and calm down I will usually be ok.... is this normal ? I know some breathing issues are normal and ur going to be out of breath more but this is like I'm struggling to breathe . Anyone else have this problem? I will be taking with my dr my next app. About itÂ
