Day 1 missed period

It’s not too late and could come at any moment so I’m not stressing too much. Usually it’s always one day earlier than predicted though. Like clock work. I’m having more discharge than usual. Like some white/creamy but mainly a lot of watery discharge. As if I was ovulating. During fertile week Discharge is excessive!!! And that’s how it is today when usually it would be little to none.. my breasts are getting more and more sore which makes me believe it’ll be coming soon. But I don’t know. I don’t want test and get hopes up for nothing though.
