I had the stomach virus Tuesday and Wednesday last week and I got the flu shot Thursday. I was suppose to have a period come Sunday since it's clock work. My tubes are tied. Should I worry that I might be pregnant.

I'm guessing you are really young because NO women past 30 can claim their period is "always" like clockwork. EVERY woman has off periods before she is 30 and will have many more after that.

Its Monday... you are only a day late... every woman is that late or later from time to time. You can't even get a reliable HPT result until you are 14 days late.

I agree with smoothy. Plus, your system is all out of whack because of the virus and flu shot. Give it two more weeks to show up.

I think the vital point here is that your tubes are tied. So the chances are almost insignificant for being pregnant.

Your period is probably late because of your stomach flu and flu shot. As suggested, I would wait about two weeks and take a pregnancy test, but don't be surprised if it is negative.
