Help 🤔🤔

So glow is telling me in 4 days is my ovulation date, how do I know I’m ovulating without a ovulation test? I don’t get paid till tomorrow and there is a hurricane coming my way and don’t know if I can grab one. Also when do people usually start ovulating? I am having lots of discharge rn. Can anyone help me?
