I've had my tubal now for 6 months and have had my cycle regularly every month. I have never had issues with cycles though, so it would depend on your body. If you are always regular... then miss a cycle, treat it like a regular non-tubal ligation pregnancy and wait two weeks for your cycle. If no cycle take a home test and schedule an appointment with your OB.
I've had my tubal for 27 years.I've been thru menapause but when I was having periods,mine were always right on time.If you're late,it could be from stress or other things.It's not unheard of for someone to get pregnant with a tubal tho.Highly unlikely but it is probable.
