Is my milk okay?

Ma

I pumped at work, put my milk in a cooler and then came home and put it in the fridge. Then I put the milk in storage bags and left them out on the counter for 3 hours 🤦🏽‍♀️🙄😩 is it still okay to use? I just put the bags in the freezer just in case. They felt room temperature. What would you do??? My LO is 7 months
