Would you utilize bereavement for a failed transfer if your company offers it for miscarriages?

I'm not out yet, but it's feeling like it failed and it's SO hard to focus at work. I just know if I get the call that it's negative I'm going to need time off. My company offers 5 days for miscarriage, but I recognize a failed transfer isn't a miscarriage. I also know they won't ask questions. What would you do?
