Back labor ? 24 weeks pregnant

Cristian

I have severe lower back pain . I tried changing positions ,took a shower ,walked around nothing is helping . I feel crampy in my lower stomach bt I don't have no discharge. Should I take a Tylenol see if it goes away or what should I do ?

I'm high risk as well since I'm type 2 diabetic and have cholestasis plus I have placenta previa if any of that matters
