Laproscopy done week ago, stage 3 endo! Walked a mile and light workout, belly button now bleeding a little! Is this ok?

Probably. Some bleeding is not unusual after laparoscopy. Put some pressure on it. If there is an issue see your doctor.
You will be fine. Some one after laparoscopic surgery walked a mile with light work out , means your are fine no inside problems , some times scar in belly button takes couple of wks , jusy wash and clean the area and go for a follow up visit to your doctor.
