Why wont this girl call me back?

i slept with this girl and haven't seen her since. I haven't called her but texed her the next day and she responded, but she never called. I have a lot women friends so im not one of those guys who will call out of control and sweat somebody. And she gave me her phone number before i left that day. I just never had somebody that would never call back at all. And ive seen the girl a few times before that night and she had a crush on me because she knows i can dance. But i would like it if she picked up the phone to call. And i want to call but i really don't want to seem like im sweating her or blow my chances of meeting again (it was that good last time). its been a week exactly, should i call or not, or text or what.
