Terrible legs cramps! Help!

My leg cramps (primarily around my upper thighs and hip area) have been terrible the entire 3rd trimester. I can't even walk sometimes. Anyways now I'm thinking I might be having early labor symptoms and it's really hard to go through these contractions with my legs tightening up everytime I move. Help?!

Edit: also I drink a lot of water so Idk what's wrong🙁
