Just moved a few hours from where my dog grew up and she won’t poop

I’ve had her since she was about 10 weeks old and we just moved from a house to an apartment (about 5 hours and a state away) after 5 years. She has yet to poop and I’m worried! There is a dog park in the complex so I let her off leash to see if that would help and we stayed for a good 30 minutes and nothing. She is not used to a leash but has not seemed in bad spirits about it and sticks close to me (she’s always been this way, even off leash). But now she just doesn’t have free rein of a yard. Should I be worried?
