Had unprotected sex 2 days ago. after taking my birth control pill today i vomit it 5 minutes later. can i get pregnant? what do i have to do?

Yes: This would be the same as missing a pill. Take another pill as soon as possible and use condoms as backup for the rest of the pack.

You COULD be....: Depending on what day of cycle you are in. The vomiting may or may not be related to the pregnancy. I would wait a few days and take a pregnancy test then follow up with your health care provider to confirm or determine other source of vomiting.
