End of period

Liz

How do you know if your period is over or if you still have it. I usually feel I have it for like 5 days with a little bit of leftovers for like a day maybe 2. Do you consider your period over once you no longer see anything or if it's really just left over stuff if you know what I mean? I've never been able to truly figure it out and I really want to know the correct ovulation day.
