Help Please! - 33 Weeks 5 Days 🎀

Alright so this is the second night/early morning that I’ve been awakened due to back pain. It’s in my entire left side and it’s a dull achy pain. I did contact my doctor and she doesn’t seem to think it’s serious. After asking me some questions, it sounded more like constipation and a little dehydration. Now, it’s no longer pain in my stomach. It’s more so just my back. Any ideas of what this might be?

P.S. I do have my next appointment on this Wednesday.
