Dump or keep?

I was pumping around 2am and my son started crying so I fed him directly from my breast and left the pumped milk on my desktop because I wasn’t finished. I ended up falling asleep with my son and didn’t wake up till around 7 am so it had been sitting out for 5 hours. I don’t necessarily need it right away, I’m trying to stock up on breast milk and store it in the freezer. I pumped 4.5 oz and as soon as I woke up I put it in the storage bag and put it in the freezer. I’m just conflicted if I should keep it. When I googled it said breast milk can be left out for up to 4 hours…other sources say 4-6 but I’m not sure. The milk looked fine and didn’t smell but could it still have gone bad? Would you guys trash it or keep it ?
