TTC, CYCLES WHILE BREATSFEEDING

So I’m spotting 6 days roughly after my period ended. First time this has happened and I am 13 months pp. still breastfeeding and we did breastfeed an increased amount last week due to my daughter having a fever. Did an LH test, negative. Pregnancy negative. Ovulated today or yesterday? Implantation bleeding from possible early ovulation? Anyone experience this?
