First time pregnant!

Ok I have been to the hospital for cramping and back pain , they did a swab to determine preterm labor it came back positive. Although I’m not dilating or having contraction two weeks later which is now I’m still having pain like stabbing but is just on one side like it hurts contanstly mostly when I’m up for a long period of times or walking even laying down. My back sometimes is all hurting or I feel pressure in the opposite side. I don’t know what to do , I feel awkaward going to the hospital & hearing the same thing. Is there any advice?
