I finished taking augmentin (amoxicillin and clavulanate) last fri. my period was due wednesday but hasn't come yet. i'm just wondering should i test o is it the tablets?

Take a test: Antibiotics should not delay your period. Home pregnancy tests are very accurate. They are the same tests used in a doctors office. They can detect a pregnancy 7-10 days after conception. The best time to take one is when you miss your period. If you doubt the result you can repeat it in 1-2 days. If you were pregnant the hormone level would rise enough for detection.
