Thanks for posting your question here, I will try to answer it to the best of my abilities.
60% of women have an egg ready to go on the last day of the break, which means that if you take the pill even a few hours late on that day, there is a chance of getting pregnant.
As such question yourself did you take the pill at the right time? If not, well take a home pregnancy
test in a couple of days. That should let you know what to expect.
I hope this answered your question.
