I’m 34w pregnant about to be 35 tomorrow but all of a sudden I’m having trouble breathing.

I’ve been cleaning the house all day and afterwards I ate and just been having trouble breathing. I usually get like that when I eat a lot mostly just short out of breathe but this one feels like someone is literally sitting on my chest .

Idk if I’m getting sick or something the last few days my throat has been really dry even if I drink so much water it’s always dry and feels funny like I’m about to have a cold . And today this trouble breathing occurs never experienced it before . Besides when having a cold .

Thank god I have a doctors appointment tomorrow now trying to find a comfortable way to sleep . Ugh I regret even cleaning today lol what if that caused it .
