TMI (no pic) is this implantation spotting?

I'm 7 DPO. Just went to the bathroom and had a little bit of brownish colored spotting. Not much at all, just enough that I noticed. There is just a very very little amount of very light pink tinged spotting when I wipe. Nothing major and it wasn't there earlier today. I typically don't spot until a day or two before AF and I'm not due for her until May 1st. Could this be implantation spotting? ​
