Cockroach yuck!!!!

So my partner and I took a beach vacation to SC and just got back. When we came back I just opened my bag and there was a HUGE cockroach inside. It disappeared and we just found it about 5 - 6 hours later. We caught it and flushed it down the toilet. My concern is wtf if it laid eggs?! What are the odds?! Are we okay or what I should we do?
