Period and Pregnant?

So I'm becoming super frustrated with my body lately. This month my period was four days late, as I had a head cold. When my period did come it was actually a whole lot lighter than I'm used to and the blood was pretty much brown the entire time. Other than that, I feel like I've been experiencing nearly all of the early pregnancy symptoms, nausea, tender breasts, fatigue, body aches, bloating, feeling hot, etc. I've already taken two hpt that we're both negative but I know my body and know something is not right. Has anyone experienced bleeding during early pregnancy? Particularly women who have PCOS or symptoms of of the disorder, since I have had horomonal issues in the past.
