5 days late, my boobs HURT like barely touch and I wanna scream hurt, I've been sleeping more, and certain foods and smells make me nauseous. I've had really random backaches and headaches, and I went from pretty much no acne to a pretty decent amount on my face and neck. I haven't taken a test because I was waiting for after my gyno appointment to try and get my periods back to normal (I only had one depot shot on July 30 and never got the second on October 30 because we decided we wanted to try for our rainbow baby. I have been on and off bleeding brown/red blood until January 11 when I started an actual period that lasted till February 1st.)

Could I be pregnant or am I just over thinking things?
