Period allergy???

So I came on here to see if there are any other girls on here that have something I’m going through. Every time I get my period my vagina has an allergic reaction to the pads I use. I use kotex U regular pads. But my vagina ends up getting this irritation and itchy burning after the first day of using them. It later turns into a rash-like situation, super dry, super uncomfortable AND!!! It starts to smell really really bad! If anyone can help me out with this situation it’s greatly appreciated 😩🙏🏼
