Signs of labor coming?

Jessica
Due on the 23rd. This morning started having light contractions (feel like Braxton hicks but with cramps) that last about 40 seconds. This has been going on every 45 mins or so. Now they are coming on a little stronger and with some back aching. I have not had my water break and only lost a small amount of my mucus plug the other day. Wondering if this could go on for a while or if I may be looking at Labor soon? I'm also having some diarrhea. (TMI sorry!) 😕 Anyone else going through this?
