3 days late....HELP 😒

Alexus

So I’m 3 days late on my period (NEVER HAPPENS) I’m always on time like clock work. I’ve been off bc since October but the weird thing is, ALL NEGATIVE pregnancy tests. WTF!!!!!!!

What is wrong w/me?!?!?! I’ve had consistent periods every month for my entire life lol!!!!

Could I be pregnant? Has this happened to anyone else lol.
