If you haven't even missed your period yet, it's very, very unlikely that what you felt was quickening. That usually occurs about 14-15 weeks into your pregnancy.
Just wait it out and see if your period comes next week. If it doesn't, I suggest taking a First Response test. I took mine the day after my period was due and I got a clear, accurate result. I've heard good things about the digital tests too, but they're kind of expensive.
Best of luck.
