Implantation bleeding?

AKY • Mom to Jonah👶🏻 & Dudley🐶

Yesterday was 11dpo. When wiping at night I had the smallest brown discharge and light cramping. I have crazy irregular periods and OPKs give me false positives regularly, so it's near impossible for me to know for sure if this is just spotting for my period or if it's implantation bleeding. I know implant bleeding is super weird, so I assumed it was period spotting. But here I am 12 hours later and AF hasn't shown up yet. I am still expecting AF, but now have the smallest sliver of hope...

Anyone experience anything similar?
