Haven't heard from my girlfriend in several days, is this okay?

My girlfriend's phone broke and a new one was being delivered a couple days later, it's now a couple of days after that was to happen. Since then I've seen a couple of online posts of her regular routine at home.

She works long hours and our work schedules conflict with each other, plus we live about 30 miles apart, so we don't see each other everyday. I've messaged once a day the last 2, so I'm not blowing up her phone, to see if she got her new one, but no messages back.

It just feels like I'm being ignored. We've be6 dating a few months and it was going well up until this. I've had plenty of bad experiences in the past but this relationship seemed different from the start. Now I'm nervous what she's going to say when we do speak.
