What are my chances?

Sorry I know some people get a bit peed off with these (am I pregnant? ) kind of questions but I really wanna hold out till at least a week late for af before testing! Any who I'm a day late I've not really had any symptoms just more firmer breast and bloat, little tingle sensation in my nipples and I couldn't stay in the shower long as made me feel very dizzy just really want to know is what are my chances this month? Also I've never had a late period before.
