11 pp and breastfeeding

I am 11 months pp and I’m still feeding my baby. I haven’t had AF yet. I was having mild cramps that lasted about 2 weeks about 2-3 weeks ago I thought it was AF. On Wednesday I had some spotting and I guessed it was AF so I used a tampon. I didn’t need the tampon as it was very light but I wore a pad thinking AF will probably start and again this wasn’t needed. I had zero pain or cramps. Now I’m thinking could this be implantation bleeding. We bd under 2 weeks ago. It wasn’t protected.

Anyone else getting spotting like this before af came while breastfeeding? Here is a picture of when I wiped this is what I was getting!!!
