TMI WARNING!

Lost mucus plug today. Woke up and felt baby drop was feeling great! Then I took a nap woke up contracting pretty intense. Waiting a while then called the doctor because the contractions were so intense. She said track them and if they continue to come into well right after I decided to get in the shower and lost my mucus plug!! I'm definitely in the beginning of early labor I'm 39weeks and 1 day and contractions are lasting about 1 hour and about 5 to 10mins apart! How long would you ladies wait before going in OB said to
