I usually have a very regular 26 day cycle... I was two days late for my expected peiod. I had extremely light bleeding for 3 days. Barely covering the tip of a tampon each day. Color ranged from dark brown to some slightly red but mostly light pink blood. Anyone experienced this?

1 to 3 days yes I have no need to worry

No need to worry about what? Are you talking about the baby being OK?

Your baby will be fine. My implantation I believe only lasted maybe 2 days.
