I need your guys help

Okay guys I need your help! For the past week or so I’ve been feeling extremely nauseous even throwing up a few times randomly throughout the day, super sore boobs, my period isn’t due until March 1st but yesterday morning I was having light pink blood super light only when I wipe and when I put a pad on it only had a small size of old blood after wearing one for almost a day.. it stopped last night and then came back late this morning but it’s been super light again and even lighter than yesterday because today there was barely even a drop today when I put a new pad on. Now when I wipe its light pink mixed with a brownish color. Has anyone experienced this before?
