Hi, i am just 17 and was wondering does the antibiotic im taking interfere with the contraceptive pill. I am taking erythromycin (antibiotic) and have been taking it for 4 months now which is long term. I checked with my doctor and she said i would be covered and it wont interefere. But i am just curious if she is right, i no she is a doctor but, please help !

Thankyou
