Labor Signs

Hello! I am 36 weeks, had my cervix exam yesterday I am dilated to 1 centimeter so things are on the move. Had a couple questions. After my exam I had cramping and spotting immediately literally right before I even left the dr office. I believe my mucus plug also came out this morning. Now I have started having loose bowels. Are there any other signs of labor? Am I just overthinking this? I am waiting and watching everything more carefully right now. Last week I have had times where I try to stand and cannot straighten out due to pain etc. This week I have not had that. Has anyone else gone thru this or is going thru it? Thanks for any and all advice. This is my first. Due date December 10th.
