Early menopause?

So i had my period on November 16th and me and my ex had sex a few times around ovulation. But the thing is I had my tubes tied a few years ago so I know I cannot be pregnant. I took a test not a fmu and it was negative. Here it is January 7th and I still yet to have a period could I be going through early menopause? Or has anyone else that had there tubes tied been through something similar. I know it is very slim your tubes grow back.
