Safe to freeze still ?

I have breast milk from 2/16 that I didn’t use or freeze. Normally I freeze same day if I know it will not be used within 2 days. My daughter has the flu so she didn’t go to daycare (only take she takes a bottle). Anyways I am not sure if it is ok to still freeze this? Or am I past the window and should I keep it for milk baths or something instead? Thanks.
