You : You could be pregnant. Some antibiotics can make some types of birth control pills less effective. Additionally you indicated that you had unprotected sex. Common signs of pregnancy can include: tenderness of breasts to include nipples; breast enlargement; lack of a period, feeling tired; nausea; mild cramping; having to urinate more often, food cravings and sometimes insomnia. You did not mention if your period is late? If your period is late; take a pregnancy test. Good luck.
