This is the dumbest question I've ever seen. U can't just stop your period for a day and then let it carry on. Once it starts it'll go until it's finished. You're a child so your periods will be irregular for a while.
As someone said by the time it's Saturday it will be a lot lighter naturally so let's hope it won't be a big deal. Meanwhile try to exercise and drink plenty of water. It helps improve blood circulation and this may make your period shorter so you'll probably be done with it before Saturday. Anyway you sound very young, so please when you feel the need to discuss these topics always talk to your mom or an adult you trust in real life. Take care and good luck :}
You aren't serious? You can't schedule that. Tampons just absorb the menstrual flow .. not stop it. I think you need to talk to your Mom about this and get more education.
Your period will last for as long as it takes. It's just the way of the world and there's nothing you can do about it, I'm afraid.
Why are you asking guys to help?
You can't be serious.
Oh yeah she's serious, dense , but serious. lmao :)
