Can i stop my period to swim or swim with it?

I need help really fast. I have to go swimming with a bunch of guy friends tomorrow but I started my period to day and I was wondering if there's anyting I can do to stop my period or block it or keep it down for the whole day or it is ok if I swim while...

I'm menstruating?

I'm not quite sure how to answer this since the obvious answer would be to use a tampon, but it sounds like that is not an option for you. In that case, there really aren't too many other options unless you are willing to use another product that has to go inside but isn't a tampon. The is a product called Instead that is an extremely thin clear flexible 'cup' type thing with what looks like a diaphragm connected to it that goes inside and forms a kind of seal around your cervix and will hold your period back until you remove it, but you have to be careful not to bear down unless you are using the restroom because it causes it to shift a little and it will leak. If you don't bear down it is pretty secure and is designed to be worn for up to 12 hours unlike tampons. I hope this helps!

can you wear tampons? If you can, you can put in a tampon, and it should be ok esp. if you can change it one or two times. If your flow is really really heavy, you might want to stay home.

Yes tampon is your only answer unless you reschedual. I would reschedual only because of the bloatation feeling and water would more than likely make me ill plus we're at our worse when our period visits us.. think about that.
Tampon but fallow the directions on the box and be careful to get toxic syndrom.

wear a tampon!!

Get a big size tampon! Usually water will stop you from bleeding anyway though! x
