What Causes Delayed Period And Breasts Soreness With History Of Tubal Ligation?

I am 42 yrs old and had bloodwork in September that said I was not pre-menopausal I also had one ovary removed in September nothing else had been removed. I had a tubal done 16yrs ago (banded) well I m now 2 weeks late and I ve been nauseous, breasts are sore, I stay very tired and stay hungry and been achey. I am very healthy otherwise. Any thoughts?
