She updated her dating profile

I (24M) have met a girl (20F) through tinder a month ago and have already gone on 4 dates. One of those ended with sex. All of those dates were good and so far there has been no indication that she doesnt like me... Except one. I have noticed twice already in the past two weeks that she has updated her dating profile. First with a picture and now with some new info and changed her status from "im not sure" to "short term, open to long". Im feeling quite anxious about it because i dont talk to other people because i like her very much. And i dont know how to interpret this
