I was in Girl Guides and also volunteered as a leader. On the health forms for the girls they always asked if the girl had started her periods, and if not, if she'd been told about it.

Wow! I rather suspect your gran had minimal knowledge of female anatomy. Sadly, I'm not terribly surprised. For the record: While I'm sure you all know this, just in case you have someone who asks you, tampons can't get lost inside you. There's nowhere for them to go. You can't put it into the wrong hole - the anus is too far back, and the urethra is way too small. (Trust me. I have catheterized women. It's hard enough to find the urethra when you are LOOKING for it, and the urinary catheters are a fraction of the size of a tampon.) The opening in the cervix is far too small to let a tampon in, and the vaginal muscles keep it in place. Women who have had babies, even, use tampons without issue. (Often the cervix stays permanently slightly open when you've had children - obviously, if you become pregnant again, the mucous plug will close it off.) Sorry if this is kind of gross, but I once cared for a young lady who had had the string come off a tampon so she couldn't reach it. It had been in there for four days. A pair of forceps sorted the problem in less than five minutes. It had not gone anywhere. She was given a prescription for antibiotics and sent home. If in FOUR DAYS it didn't manage to go anywhere, it's not going anywhere in a few hours. There is also no way for a tampon to cause appendicitis even if it did get into the abdomen, because it would have to go through the peritoneum (membrane that surrounds the abdominal cavity), somehow get into the GI tract (and if your bowel is punctured you've got bigger issues than appendicitis!), and make its way to the appendix. I know technically we aren't supposed to give medical advice, but trust me as a nurse with a master's degree. That doesn't happen.
