Ok so my question is that I started my period a few days ago and it just stopped and I didn't see anything.?

This happens to me all the time. I will have my period for 4 days, stop for a day, then restart for 2 or three more days. Nothing to be worried about. :)

Everyone is different. Not all of us bleed on a constant basis all day. For me, I more so bleed when I use the restroom, which I do a lot when I'm on my prd. Or I'll bleed just a little bit & then a LOT & back to a little. It sounds perfectly normal. Nothing to worry about. :)

You could have a lite one this time. When I start I can bleed for a while and go a few hours with out anything and then a while later have blood

Alot depends on your age. if you are nearing the age of menopause then yes that can happen. i recently went 61 days without and then boon there it is just like a normal period. always a good idea to start keeping track on a calendar so when you do see your doctor you have it handy.
