I've been using Tampax Pearl tampons for sometime now and I have had no problems using them. Recently when I have used them I have been developing a bad irritation immediately after insertion. It does seem to go away after an hour or so. I'm wondering if I could be allergic to this brand I'm using. Tampax Pearl Unscented. Has anyone else had this problem with Pearl? A friend recommended that I try using Kotex U. Should be getting my period soon! What should I do?
