Should i go to labor&delivery?

As I posted last night, I had a significant amount of bleeding after sexual intercourse while losing more of my mucus plug. I have continued to lose it today, I now feel like I'm going to be sick and got a major hot flash. I'm trying to drink water but it isnt helping. My body feels heavy, like it's hard to type this and hard to get up. I feel as though I'm going to faint. Now I have this constant pinch in my vaginal area on just the right side. I still have some spotting but only when I wipe. Is this a sign of labor? What should I do?
