roaches???

So I used to live in a house infested with roaches. We moved twice and now have lived in an apartment for 2 months with zero problems with roaches.

Well I just got up and saw a medium sized roach on the wall and I killed it.

Are there more? I'm freaking out because I'm being induced tomorrow and seeing any kind of roach gives me the BIGGEST bout of anxiety. Should I tell the apartment manager?? They do pest control where they'll come in and out some stuff in the kitchen and whatnot. I'm freaking out and I feel disgusting and I do not want an infestation again. Especially not with a newborn.

Please somebody help me. It's 3am and I no longer can sleep because I'm just checking everywhere and having an anxiety attack.
