What to do after the first kiss?

So, Saturday night I finally made out with my crush. We were sitting in her car and I leaned over and we kissed. I thought it was passionate and after we began we started pushing each other in different directions, I got out of the car probably 4 times only to get back in and kiss her again. lol. anyways, my question is, after that night I texted her twice the next day casually, I don't want to be creepy. She never got back to me! I didn't call or text at all the day after that but now I am thinking I should tell her how I feel because I can't get her off my mind. We were friends for a good month before, hanging out almost everyday by ourselves. and I know she is a tad bit of an uncomfortable girl. but our first kiss seemed so right! what should I do? what is she thinking? I really want to open up to her.

I should probably add that we were both drinking that night at a friend's art show, but I sent her signals all night. we've been sending signals back and forth
