Advice? Missed period?

Okay so pay no mind to when i logged. But it says im three days late right? My period has been coming earlier and earlier. So i feel as if ive missed it. What should i do? Wait this week out & and next week? When should i test? I get anxious. Usually my boobs get a bit tender before period but ive got nothing so far. Ive been a little moody. Ive been nauseous. It's been almost a year since the removal of my paraguard. I havent really been trying. But if it happens then it happens. Then it was meant to be. ❤
