just a one night stand but it felt so much more

so yeah i was out last week and met this girl at the club. we hit it off really well, danced together, drank together. i could tell she had chemistry with me too, so after things calmed down, we exchanged numbers. next day we met up, went to her place and... well you know what happened. it felt different though, like something more than just a casual hook-up. im not sure if its the trans aspect or what but usually im okay with being casual, no strings attached, but this time i felt weird afterwards. am i reading too much into it? i dont know if i should reach out to her again.
