Question about a girl

So I got matched with this girl a couple of weeks ago on Tinder and I went on a dinner date with her last Sunday. After the date we were constantly texting, we texted everyday even if it was only a couple of texts. She invited me over to her place to watch a movie late this Sunday. We watched the movie and then we kissed and did a bit of hand stuff. I offered her a massage and then we had sex. She seemed really into me, we cuddled pretty much the entire night. Monday morning I texted her thanking her for an awesome night. She hasn't replied to my text yet. Does she no longer want to see me? I may be overreacting but she may be mad at me for staying after the sex, she told me that she doesn't usually like sleeping the same bed with other people and neither of us really got a good night of sleep. Am I overreacting?
