34 weeks

Crystal
I'm 34 weeks 2 days went see my OB on Tuesday and baby measured 5 weeks under but weighs 5lbs go back in 2 weeks to give blood why idk was already dilated to 1cm haven't been checked since . Was told come back if the pain and pressure gets worst but only my back started to hurt more . Could the contractions be in my back ? Will she be inducing me if baby still measures 5 weeks under and uterus not growing ?
