Blood test

Ok so I went to the doctors like the first of this month for all my blood work and to get tested for any std's. Which I'm positive I don't have any but in case I did wouldn't you think they would call me right away to start treatment? I haven't had a call about it and i don't know if I should worry or not. My next is appointment is on the 27th so I'm hoping they wouldn't make me wait that long if there was something serious.
