Okay so I have to wear tampons when I start my period but the problem is after 3 days of wearing tampons my vagina starts to get sore and really hurts. I use smaller tampons but they hurt just as much as my super plus tampons. If I don't wear a tampon I bleed through a pad within the hour and at work I need to wear tampons. Basically I'm wondering if there's something seriously wrong with me downstairs or if it's normal to be sore.
