should I go now?

Isabel • Anything can happen
So all day today and partially yesterday I've been having this pain in the middle of my stomach, like a sore feeling. Every time I try to get up from bed, walk or even move it hurts, I have been feeling my baby not move as much as often and this morning as well as right now I went pee and this showed up. Could this be my mucus plug or something else? Should I go to the hospital this is my second child and this pregnancy is toatal y different just as expected, but I'm slightly worried-help?
