Brief Answer:
Pregnancy is unlikely

Detailed Answer:
Hi
Thanks for choosing HCM for your query.
Incomplete data like age, gender, presence of other illness like gastritis, drug intake, alcohol intake, etc.

I have gone through your case scenario carefully, despite of vomiting following the intake of Plan-B on two separate occasions, some how you could retain on the third attempt of Plan B and that too with in 72 hours of unprotected sex, so that one dose is sufficient enough to prevent the unwanted pregnancy.
Therefore pregnancy is unlikely.

If you still have a doubt, then get the urine pregnancy test done if you do not get your period on time.
I hope your doubt has been clarified.
Wishing you best of your health.
