Hey y’all HELP!

I’m 3 days late ( was supposed to start Tuesday and it’s late Thursday if that’s 3 days??) but super crampy. I had spotting like 3 days after my period but i didn’t think it was IB. Today on day 3 late, I had white discharge. Anyway how long should I wait to take a test?? When would it be accurate?! My husband and I are sort of not TTC but also try a little cuz I have MAD baby fever! 😂😂😂
