What is wrong with me?

El

So I’m just curious as to why I’m feeling weird down there. I’m not new to periods by any means but doesn’t anyone ever feel odd or uncomfortable with their period. I’ve never had this before but yesterday when my period started my insides started feeling dry and kinda off, almost itchy, similar to a uti but not really. I don’t know if it’s maybe my PH or what but it just feels off and I’m wondering if someone has had a similar experience to this. Also I haven’t been sexually active in like a week if that helps clarify anything.
