honey, i would go to the drugstore such as cvs and get a pregnancy doctor.. or the best thing you could do, is talk to your mom. she may hate your ex but if youre 14 years old, she legally cannot kick you out. just talk to her about it. i know it will be scary at first, but once you do talk to her, you will feel so relieved, and ask her to bring you to the doctors to get checked for two things: pregnancy, and to make sure you didnt catch any sexually transmitted diseases.. good luck!
