Michelle,
Is there a close friend who could help you purchase and take a home pregnancy test? If not I would contact Birthright or a local crisis pregnancy center. Most will do free and confidential pregnancy tests. If you are pregnant and do not want to have an abortion do not let your boyfriend pressure you into an abortion. Listen to your heart and do not act out of fear or pressure. Hopefully the result of the test will be as you want, but if you are facing an unexpected pregnancy the crisis pregnancy center should be able to help you to break the news to your family. Hang in there. Best wishes.
Kate
