Spotting or implantation

Merissa

So we've been trying to get pregnant for a few years with no success. The last ofnmy period was Sat, Sun we did the dead & today I've had this brownish spotting. I've never seen this before. Usually I'm either bleeding brown or red or nothing at all.

Could this potentially be implantation, could it just be "left over muck" as I've heard it called before or something else entirely. I know to get 100% correct answers I need a doc... I just can't afford to run to the doc everything my body something odd. Therefore any and all advice is welcomed.
