Should I call?

I got an email from Debra on the 11th band couldn't respond till the 13th due I midterms. She asked me when I was available to talk this week and I said whenever works best for your schedule. And she has yet to even reply. Should I just call her?

It's pretty early in the week, and she's extremely busy. If you don't hear back from her by the end of the week, then I would give her a call.
