Am I pregnant?

I’m 17 years old and I take the pill every day at the same time. Me and my boyfriend have sex quite frequently and without a condom. I recall throwing up after I took one of the pills this month so maybe it wasn’t absorbed. I started my 7 day break, three days ago and my period didn’t come. I’m starting to get worried because normally it would have appeared by now. I still have four days (counting with today) until I start the next package.

Is it possible that I’m pregnant?

What are the odds of me being pregnant?

Please answer me
