mucous plug?

so 40 weeks + 2 days. been having irregular Braxton hicks? (stomach hardens and feels like period cramps, somtimes felt in lower back too. not painful, just irritating) since last night and through today. just had sex to try get things going, and immediately after when I wiped the tissue was pinky red. after I peed and wiped it was light red blood streaks. mucous plug or should I call hospital?
