Stomach bug?

I had a friend invite me over today, then as soon as I got there she informed me her two year old had gotten sick that morning. He threw up several times while I was there, but never very close to me. I was careful to not touch anything, and I left after about an hour. As soon as I got home I stripped my clothes off, washed my hands, and hopped in the shower. I then sprayed my house down with a disinfecting spray. Do you think there is any chance I won't get it? I'm 17 weeks right now, and very concerned about the wellbeing of my baby!
