Thawed breast milk

Hello ladies!

So I have recently started to use my milk stash as I have no supply anymore and I noticed it has a strong fishy odor 🥺 I’ve read it can happen but I’m still nervous to give this to her. I tasted it to make sure it didn’t taste sour and it doesn’t. It taste slightly sweet with an overpowering fish oil taste after. What am I supposed to do ☹️ she takes it when I give her the milk but I’m still wondering if it’s okay. Please give me your thoughts/experiences/recommendation! Thanks so much!
