What’s going on?

R.

My last period was from June 22nd-27th. While in my fertile window, I ended up getting on the depo shot July 2nd, then had unprotected sex the following night-July 3rd. I lightly spotted for 2 days in a row which happened to be a sort of pink color, my boobs became sore for about almost week. I am 13dpo and my period is late by 1 day... I tested yesterday and it was negative. Any advice? Will AF show up?
