Weird smell??

During my period I got kind of a strange odor from my vagina, but I didn’t think anything of it cause I looked it up and several sites said that’s normal. But my period ended a couple days ago and the smell hasn’t gone away, should I be worried? I had sex a day or two before my period ended but it was protected.

Am I worrying for no reason? I have no other symptoms of something being wrong other than the odor.
