No form of birth control is 100 percent. So of course you could be.

But also your body can be confused because of going off and coming back on the shot.

By most standards 2 days is not really late, many women are off a few days all the time.

There is no way to tell at this point, you will need to wait and if no period in 14 days, try a pregnancy test
