Expired preseed- ok to use?

[Bizawit]

Hi all, I have a packet of pre-seed expired in Nov 2019. I’ve just started TTC again and wondering if I can still use it? Seems like such a waste to buy a whole new packet! Any ideas?

Was it still sealed? Then I'd prob use it. If not, not. You don't want any air contaminating it, or you might end up with thrush.
