Welcome to womanhood! You would be happy to know that almost everyone goes through this phase of embarrassment, I certainly did. The thing to ask yourself is, do you notice other people carrying pads, tampons or liners in the supermarket? If you do, do you feel that those people should be embarrassed? For me, the answer to both of these things is no. Of course, if you are still embarrassed, get your mum or a friend to buy them for you or to go with you for moral support. It is also helpful to pick out the female cashiers and avoid the cute boys from your school who happen to be working.
