Help a girl out...

For the past 3 hours I’ve been having lots of pain on my entire belly and it’s felt very hard off and on. I can’t tell if they’re real contractions because my belly doesn’t seem to go completely soft. At my last appointment I was 3 cm dilated and 40% effaced and that was at 36.1 weeks, today I am 37.2 weeks...

Should I call my dr office ? Please help, FTM
