Is it normal to have constant backpain at 35+5 weeks pregnant? For last hour and half now I have very very bad lower back pain, I've tried to lay down and walk but it's not going away, my stomach feels very hard and tight as well & I have been getting very mild not frequent cramps I my abdomen but this backpain is something else its soooooo painfull, it goes to the side as well but it just won't go away
