I am a month late on my period I have taken several test and it says I am not pregnant and now I have a smell coming from down there, can anyone help me

We can't diagnose you over the internet sweetie, although we'd love to help any advice we give would just be a guess, and that's not going to help you. It's time to go to your doctor and have this looked at.

Good Luck.

There are 100's of reasons for no period and for "smells"

It is time for a trip to your doctor.
