I'm having all of the pregnancy symptoms, at least I think so (sore boobs, headaches & nauseous). I also was spotting (light pink) the day before I had the brown discharge. Yesterday, I thought I had got my period because when I wiped it was red so I put a tampon in. When I woke up it didn't even fill up the tampon. It was a little bit of red w/Mucus. I decided to take a pregnancy test but it came back negative. I'm really confused.
