37&3 in labor??

Lastnight I had some pretty intense contractions they started around 3am and I started timing them and they were 5-7 minutes apart. I stayed in bed hoping they would go away, but they lasted until 730am. Around 10am I got out of bed and having little contractions but nothing like lastnight and horrible lower back pain. At my last dr appointment I was already dilated to 3cm. What should I do? Wait it out until they get really bad or am I in labor already? My water hasn’t broke yet either. Right now I just feel nauseous and my lower back is killing me.
