Implantation bleeding

Have any of you ladies experienced implantation bleeding? If so what was it like? I saw a small amount of brown blood In my underwear this morning and got really sad thinking it was AF two days early, but then when I wiped there was nothing else. Cramping isn’t as bad as if it was the first day of my period but idk if that’s just in my head, and my CP is high/medium and soft. Any insight would be greatly appreciated! I’m also 11dpo. AF is supposed to arrive sometime between tomorrow and Monday.

Thanks in advance!! Baby dust to all!
