If you’ve tried to insert a tampon and you’ve followed the instructions on the box that they came in and you still can’t get it into your vagina, you should make an appointment with your health care provider. Some girls are born with a very small opening in the hymen, which prevents them from inserting tampons. However, this is true in only about 2% of teens. Others are just nervous the first time inserting a tampon and need practice.
