12 dpo and getting anxious

Shawnee
So 3 days till AF is due and im getting worried that if she does come I will get upset and really emotional like every month. I have my usual sore boobs which feel like theyve grown but I always get that with pms. Ive had a few extra symptoms I dont usually get, throbbing headache on one side of head for a couple days, feeling really fatigued. Im starting to lose hope every month af comes. What do u think my chances are?
