Cum (semen) or Discharge??

I had sex a couple of hours ago and we used a condom, I’m sure he did not cum in me and everything was okay with the condom. It is now like 5 hours later since I’ve had sex and I felt myself getting wet down there so I checked it...and it was like white liquid, it felt like water and it didn’t really have much of a scent. I’m a little nervous though because I did have sex today, could this possibly be cum (semen) or just discharge??
