TMI: freaking out need to know what's happening please help

I wanted to know if this has ever happen to anyone and they still came out to be pregnant. I went to the bathroom and pee afterwards I wiped which was a light brown discharge. And still in bathroom a whike wiped again and nothing. My period isn't due till Dec 22nd as you can see I've ovulated sometime last week. Not sure how many dpo I am tho, I'm not cramping or anything although my Boobs are sore hoping it's cause I'm pregnant but scared when I saw this.... it really doesn't have a smell to it either took a test today it's was negative so not sure what's going on please help me
