How does STD testing work..

Okay soo I found out my boyfriend cheated on me (I'm pregnant) we broke up and everything but apparently he cheated on me with MULTIPLE GIRLS.. at least 3 and I'm scared I might have something now.. I don't have any symptoms but I want to get checked out for my baby incase that would harm him? If I go to the clinic on Monday do you normally get results that day or how does that work...😕 also this is pretty embarrassing I got checked a year ago but I don't really remember the process
