Advice needed from all you mommas to be!

Breanna • Walker Ray 💙
I figured I'd ask since you ladies are already pregnant. I just took a HPT and got a faint line (I'll post a picture). Everyone on here says it's definitely positive. My AF was due today and all I have is light brown CM, what could that be? The test definitely looks positive. I want to surprise my SO today when he gets home but I want to be sure before I get him excited. Advice please and thank you!
