Ever since i got my first period, i have weird post-period odor but no discharge, irritation or anything, just weird odor. it lasts a couple of days and then it's fine. i shower every day, products i use aren't a problem. should i be concerned then?

It must be at least 6-7 years since your first period, right? With no change over that time and no other symptoms, probably this is entirely normal for you. However, be careful about genital area "products". No woman should douche, which is harmful and markedly raises the risk of bacterial vaginosis and other health problems. And no perfumes or other "products" inside the vagina. OK externally.
