9dpo symptoms?

I'm 9 dpo and my period is due to start tomorrow, my breath are so sore and my nipples are super sensitive 😭 I've not had the usual cramps to suggest AF is on the way so really hoping that this month is the month she doesn't arrive 🤞 my lower back has been achy also anyone else experienced this? I have dine a test and it's negative but I know its too soon, just hoping
