no you can not go swimming when your period is heavy. When it is at they very end and its not that heavy your period will not stop in the water, but will be held back. Also, if you go swimming and you have your period when you get out of the pool it might start to drip down your leg.
if your on your period before your date then go swimming so it might stop quicker, it depend if it's heavy or not if it's light it will stop but if it's heavy it won't work
No, your period flow doesn't stop in water - this is a myth, there is nothing about water that will stop menstruation. When in water what little blood leaves your body can be diluted in the water, but heavier flow may be noticed and especially so if you pass uterine tissue that wouldn't be diluted in water, once you get out the water blood will be more obvious too.
you either have to stop or wear a tampon
No, it continues pretty much constantly. Most women wear tampons when they go swimming, as the pads absorb water and get really heavy and messy.
