implantation?late period? spotting? I'm so confused?!

so if glow is correct I am about 20-23 dpo, my "period," started on the 1rst of March. it was what I would describe as a slight red/Brown blood mixed with tacky creamy like discharge. very light,1 1 or 2 small clots looked more like mucus to think of it. not really heavy enough for pad or tampon. (sorry about the tmi) that went on until the 4th of March. for the last 3 days conceive had spotting or yellow blood mixed discharge and brown/red lotiony discharge. (I'm sorry for being so descriptive) a few other symptoms are, I've been extremely tired, needing a nap almost everyday even after sleeping in. I feel like I could everything. not that I do. but I want too (:! I have a well woman's check tomorrow, but I was just hoping for some insite. please let me know what you think.
