Thank you for posting your question here, I will try to answer it to the best of my abilities.
Yes, there have been some cases when a woman doesnt get her period right away after stopping the pill. But the main chances of getting pregnant are dependent on when you had intercourse, if it was during the time when you were ovulating then there is a very high chance to get pregnant.
Anyway I recommend you take the home pregnancy
test within the next 2-3 days.
Also you should know that it is also possible that your period is running late and as such there is nothing to worry about.
I hope this answered your question.
