shortness of breath?

Cassandra
I'm 36 weeks. I had the flu on Thursday and then Friday Saturday Sunday and Monday had congestion and headaches. I am feeling better now. 
But I'm curious if anyone else is having a hard time breathing? I've also got very high heart rate. But every time I go into the doctors my blood pressure is fine. I tell my doctor and she says it's all normal I don't think it is. But I still feel baby being active and I just am having a hard time breathing. I feel very weak and dizzy when I try take deep breaths cause I feel I am not getting enough air.
Drinking water makes me feel sick and I feel horrible. Idk what else to do besides lay in bed or sit down cause anything else I feel like I just can't get enough air. Sounds dumb and silly but I'm freaking out. I loose air and my heartbeat is hella fast. Please tell me that someone else is experiencing this too and it's not just me. I've gone into the doctors office and L&D. They say it's all normal and send me home. Idk what to do.
