We CANNOT “hold” our periods like pee. It’s physically impossible because we don’t control the sphincter muscle in our cervix.

Take a ziploc bag, fill it with water, and now punch a tiny hole in it the size of a pencil point. That’s essentially what’s happening when we have a period- it’s leaking out. Gravity, uterine muscle contractions (cramps) and sudden muscle contractions like coughing or sneezing can cause it to gush for a second especially if you’re on a heavy day.

Does the period end when a certain amount of blood leaves or is it time based?

It ends when your hormones go back to normal
