Anyone else unable to stand for that long?

Anna • 22🌸 Married 💍 Christian✝️ Due in August 🤰🏻💙

Trying to figure out if this is normal or if I should bring it up to my doctor next week!

I’m 31 weeks. I can’t stand up more than 2-3 minutes before my heart starts pounding (over 100 BPM just standing) and I can’t breathe that well.

Sometimes, randomly, I feel like I’m going to pass out when I’m just sitting. Is this normal pregnancy stuff or concerning?

Thank you 💗
