Preterm labor concerns or no?

Shanta`
I'm 32 weeks & 5 days. I'm dialated 1cm with a soft cervix and lost my plug yesterday. I have really bad achy cramping pains very often. I get contractions as well but not regularly. I have severe lower back pain and feet/ankle/hand swelling. Also nausea and I haven't been nauseated since 4 months. Do you think I should be concerned about preterm labor?
