Help labor?

Hey guys I'm 20 weeks. I think I may be in labor or is it impossible to be in labor. Yesterday around 530 or 6.pm. I started have like gas pains that wrapped around my back and sides and my stomach. I was like oh ok just gas. Well then about to hours later I got to the point the pains were so bad I couldn't hardly walked I kept feeling pressure and I was practically bent over in pain and contrasting felt about a minute n half apart. Well I was crying saying I needed to go to hospital but I had my kids with me. So I figured I wait a couple more hours. I took a bath and they started to subside. Well now this morning I'm getting these pains in my back again. Please don't judge but I checked my cervix I think if I checked it right I may be 2 to 2 n half cm dialted. It felt far back but I could feel an opening. And feel like I can like feel the baby kicking my inside I know weird. What the hell is going on. Do I need to go to dr or er. I contacted dr they said I could come in at 3 for apps and that 3 hours away.
