Hi Anonymous,
Thank you for your question and for finding EmpowHER. Anytime you have sexual intercourse and don't use any kind of protection (condoms, spermicide, withdrawal, birth control pills), you put yourself at risk for getting pregnant.
You will need to see if you get your next period to know if you did get pregnant from this event. It is important you not put yourself at further risk to avoid excessive worry, and confusion. If you don't get your period when expected, you can take a home pregnancy test or call your doctor's office to request a pregnancy test.

Good luck, and let us know how you're doing.
