Could i be going into labor?

So im 38 almost 39 weeks pregnant. it started yesterday were ever since i woke up i was having small contractions they were about 5 minutes apart (from beggining of one to the beggining of the other) as the day progressed they got alot worse and i completely lost my appetite. So i went to labor and delivery and i was having contractions the whole 3 hours they monitored me but every time they checked to see if i was dialated they said my cervix is still closed. When my actual doctor checked to see if i was dialated i was almost dialated to 2. So all that has me confused. Well all last night id wake up every 10-20 minutes feeling sick and today i can barrely eat and i have a very intense migrane and diarhea. Along with contractions the same as yesterday. Could i be going into labor? I go to the doctor tomorrow and im getting induced on wednesday.
