Implantation bleeding

Samantha
So I have been trying the "not gonna think about it" meathod. And I'm on cycle day 48. (I'm always irregular). This afternoon though I went to the restroom and when I wiped I had some light, pink bleeding. Thinking it was the start of af, I put in a tampon and went to work. 3 hours later I went to the restroom and the tampon was clean. I put in a clean one bc I was at work and didn't want to have any accidents, again a couple hours later same thing. Since I haven't been keeping up with anything I have no idea if this could be implantation or what! Any thoughts? Keeping my fingers crossed for a special Christmas and Birthday present!!
