Is it good 4 a 13 year old to use a tampon?

No, tampons are best avoided and especially so by teens.

It's recommended that pre-teens and teens don't use tampons - the reason is that the younger you are the less likely it is that you have antibodies to TSST-1 toxins responsible for TSS so are at higher risk. Younger women are also often less capable of making an educated decision about high-risk items like tampons and may not be responsible enough to use tampons correctly.

It is best to use pads at first, and if a girl wants to use something internal she should consider safer options like menstrual cups or softcups - these pose no health risks like TSS or infections, also more convenient and reliable.
