Help! Am I in labor?

Consistent pain in my back and cramping in the front that comes and goes... I have pooped twice today and feel so much pressure down there! I feel hungry but can’t force myself to eat and just feel exhausted like I don’t even want to get up and do anything... I took a nap around 11 my time and still didn’t feel better and am still tired and its 3 now.

My hips hurt too! This is my third baby and I’ve never been this uncomfortable and have been induced with each of my babies so I don’t know what it’s like to go into labor naturally...

Is this just normal end of pregnancy stuff or should I stay vigilant or call doctor or what? I am 35+4 and am measuring 4 weeks ahead... have an appointment and ultrasound tomorrow to check on baby.
