So I’m 32 weeks and for a couple days now I’ve felt off. I’m extremely exhausted and that makes my head feel weird. I also have this feeling like I’m super dehydrated all the time even tho I’m drinking tons of water right now because it’s hot out. Like literally I’m drinking more water than I ever have. Like I almost feel sun sick all the time. Is this normal for the end of pregnancy? Also ever time I get up I feel like my heart is beating out of my chest and I can’t catch my breath.
