Tiny spot on undies. A little when I wiped with tp. No repeat and did not last for the day or hours. Just a one time thing. I can’t remember what the timing was like. Happened to me with two pregnancies (both miscarried).

Mine was at 4dpo just a tiny dot !

For me just a day and only like an hour it was supppper light almost peach color and brown that’s it I did have some cramping as well nothing major it was about a week or so before my period as well
