I found 2 pills in my daughters work apron. They are as small as a mini m&m, blank on one side with 100 imprinted on the other, only 100, no other numbers or symbols. I've gone through so many web sites trying to find out what they are, maybe they are generic and that's why I can't find any info. But, I would hate to approach with the intent of punishing, just to find out they're ibuprofen, or her birth control or something. Can anyone help with these?
