What is this? TMI picture.

Hi, ladies! I've had protected sex three times this month. With no accidents as far as I know. My period is supposed to be tomorrow. I've been having my normal pms. My breasts have been a little more sore than normal, I've had a horrible headache, and some acne. I got this spotting a little bit ago and it kind of looked pink/brown. Which I've heard can be related to pregnancy. I get super paranoid about these things. I'm not on birth control, we just used condoms. But I still want to know what you ladies think. Is this just normal spotting? Thanks!
