I'm 4 days late n too tired to worry

Any suggestions? AF is 4 days late, all I do is eat n sleep , my boobs r HUGE n full , I spotted about a week before AF was due, it was a light pink/brown/mucus-ee type stuff n it just went away. I'm waiting til I'm a week late to test.. Anyone else feel like this? It's like the flu but I can't stop eating! Lol
