Should I be worried πŸ˜“πŸ˜“πŸ˜΅

I'm not really sure what it is but my vagina feels irritated like its itchy..? It just started happening last night and I didn't think it was anything but this morning its still a little itchy. I don't know if its infected it something I mean I don't think I can be because I haven't put anything in there or anything like that. I showered and tried washing myself but I still feel it πŸ˜“My only guess is that I went to the movies and it was like a 3 hour movie and I was in really tight jeans with my legs crossed so I really don't know the problem. πŸ˜“πŸ˜“πŸ˜΅
