Brand new Pacman not eating

[DiamantSchekter]

Hi,

I recently purchased a baby Pacman frog over the mail and for some reason she's eaten barely anything at all (1 or 2 crickets) in my first 3 days of having her. I'm regularly misting her tank, trying to get the temp up with a bulb and heat pad on side of tank, but still no hotter than 72 or 73 degrees. I've only tried feeding her crickets so far, also not using any tongs (didn't think it was a big deal but maybe it is). Any idea if something's wrong with her, or she's just spooked from the new environment?
