Frozen breast milk tastes weird, do I need to dump it??!!

Hi,

I have expressed once a day since DS was about 2 month old and now have quite the freezer stash (about 50oz) which I planned to use on cereals, in cooking etc. I defrosted a bag overnight in the fridge and tasted some (yuk I know haha!) and it tasted like soap and a bit sicky! Is it off? Do I need to throw away all 50 oz?? I feel like crying
