Swelling

Mi

Is this normal? This is my third baby and I have never swelled before with the others. My BP is always super low (90/50s), passed my glucose test, don’t eat a lot of salty food. I have been on a work trip out of town the last three days so I’m not sure if it’s from sitting so much? I still have awful water aversion so I didn’t drink a ton of what like you should.. I have two kids so propping my feet up doesn’t happen but a second or two
