Dark light bleeding

Rebecca

So I had my son 9 months ago and ever since I've had crazy "periods" the first one I got I was 6 ish months pp and its was super light almost considered just spotting for 2 days and that was it. Now I'm 9 months pp and I'm bleeding again it's super light I'm on day 3 and the blood has been super dark the whole time. Also I got a positive ovulation test 4 days before the bleeding started.

This is the color my blood has been this bleed..

What the heck is going on?
