Maybe baby? Please read!

Light pink bleeding May 12-14, the bleeding only occurred when I would wipe, sometimes not even then. When I had the light bleeding I was super gassy, and just felt like a knot in my stomach. Is this common? The light bleeding never took up enough for a panty liner. (The picture is the light bleeding I had - a week before my period was due.) My period is scheduled for May 20-24. I am now two days light and I have no sign of AF coming; no cramps, bloating, anything!

I have been super emotional and been exhausted out of the world. 

​

FYI my period is never early, light flow like this or pink.

​implantation?
