On pill. Haven't missed one. Had unprotected sex on 14th had cramping since. Period due in 5 days??? What could this be??

See a doctor. Even with perfect usage of birth control..nothing is 100%. There are other causes of cramping though such as bladder infection, vaginal infection, ovulation, fibroids, unknown causes. If continues or worsens then recommend follow up with a gynecologist.
