Mate, I haven't read the other responses but this one is very simple. 1) you wrote "i texted her after a week since I was occupied with work" - you showed VERY low interest, too low, and played it too cool. Then 2) "She disappeared for a whole day and messaged me back late in the night saying yes hoping she gets some time off at work." - you think her not responding for one day is a big deal?!
Further, she is a doctor so she would be busy. She confirms this by "hoping she gets some time off work".
There is ZERO to read into this. Enjoy and relax.
