Braxton Hicks or something’s wrong?!

Nicole

I’ve been experiencing Braxton Hicks but sometimes it feels more like cramps it hurts so bad in my lower back and sometimes my stomach gets hard like a Braxton Hicks and then it hurts like cramps and doesn’t go away for recently some nights a few hours the other night it was so bad I couldn’t walk because the pain was shooting down my legs I’m also 22 weeks pregnant so idk if that’s normal because of everything stretching???
