Sorry about the lost tampon. It happens though. You know, it doesn't hurt and took some investigation to even find so I'd not worry. Really. If it begins to hurt, itch or smell, then you can try an urgent care telling them that you have no insurance. They often can work with you and see you on a sliding fee scale where you pay cash or put it on a credit card for less money. Or clinics can help. Planned Parenthood is another place women can go for help with their medical care when they don't have insurance.
