My surgery was nov eighth. I was supposed to start my period five days ago. I figure my body is messed up from surgery? Anyone else experience this?

I have and i believe that our bodies may be thrown off by all the changes.

Yes, in fact my periods have been messed up ever since my surgery in January. Sometimes it's early, sometimes it's late. sometimes it's just plan weird.

Weight loss can cause that, too.

I am like clock work every month but the first month after surgery I was 2 days late.
