Hi i am 5 days late and my tubes are tied. i have never missed a period or late my period always came regular is that normal?

Probably not normal: Having your "tubes tied" does provide you a highly effective method of contraception (more than 99%) but unfortunately pregnancy can still occur although quite rarely.(1 to 15 per 1000 depending on the type of operation) . Checking your blood betaHCG pregnancy test would be wise. If negative, you may want to consult your Gyn if you still miss 2 or 3 periods or if your cycles become irregular.
