need your help ladies

yesterday at night I couldn't sleep, I did fell asleep but it was one of those restless nights, so I woke up feeling something different, short of breath, tired, and as I'm was doing todays chores I noticed that I can't keep up with myself more than 10 minutes without getting this sensation of CM coming down (i go check and nada!) or that my pelvis hurting or just bothering when I'm just standing washing dishes, I'm 20 weeks+3 and I feel the baby kicks but I feel it so low and very unsettled...should I worry or this is very normal? TIA
