Missed period after sterilization?

I had a bilateral salpingectomy- both of my Fallopian tubes removed- at the end of October. Because my period has always been super regular, I had gotten my first period a few days after the surgery, just as expected.

My November period came a few days late, but i figured that the surgery may have just thrown it off a bit. Now I’m over a week late for December’s period- with random cramping since the day I was due for it.

For those who have had the same procedure- was your period normal after? Or did it take time to go back to normal?
