If you are on Birth Control and taking Antibiotics, you can become pregnant.  Antibiotics make BC pills ineffective.  You should probably take a pregnancy test.

waterskigirl is exactly right.  Take a hpt to see if you've become pg.

Do antibiotics interact with birth control pills?  

--------------------------------------------------------------------------------

Certain antibiotics can interact with birth control pills, making the birth control pills less effective and pregnancy more likely. Spotting - or ‘mid-cycle’ bleeding - may be the first sign that an antibiotic is interfering with the effectiveness of your birth control pills.
Antibiotics that have been shown to interact with birth control pills include rifampin (brand name Rifadin), penicillin (Veetids), amoxicillin (Amoxil), ampicillin (Omnipen), cotrimoxazole (Septra or Bactrim), tetracycline (Sumycin), minocycline (Minocin), metronidazole (Flagyl), and nitrofurantoin (Macrobid or Macrodantin).

To help women avoid pregnancy while taking an antibiotic - and for at least one week afterward - doctors generally recommend they use a condom or spermicide as a back-up method of birth control. If you are taking both antibiotics and birth control pills, be sure to check with your doctor about how long you should continue to use a back-up method. Also, discuss any other questions you may have about this information.
