Should I try to text her again or no?

Me and this girl have been going out (made it "official") since last Thursday. We saw each other on Monday, we hung out, watched a movie, made out, the good stuff. I texted her on Tuesday, but she didn't text back. I texted her again on Thursday, but she never texted back. I commented on her status on Facebook, she just posted "Having a bad day." (or something like that) yesterday. Haven't texted her since then yet... should I? Or wait for her to text me? >_> Don't know what to do.
