33WKs + 3 Pain on my back 😟 help

Rosalinda
I feel like this pain on my lower back and it's a sharp pain that doesn't let me move, when I sit down it hurts so bad and I try to lay down thinking it might be that I'm tired, and no it hurts more. if I try moving to one side or the other it hurts. if I try to walk, I have to walk slow because it hurts to even move. My SO massages me because the pain is so strong that I want to cry.. and he just tries to make me feel better. It only happens like once or twice a week.. the other days I'm normal like nothing. Don't know if it's just my pregnancy or something is actually wrong.. has anyone gone through this? 😥😕
