Question: I have been taking lutera for years and about 2 weeks ago i was given azithromycin to take for 3 days. I continued to take lutera during this time and i had unprotected sex a few times with my boyfriend. He never came inside he always pulled out. Now im on my 5th pill of placebo and i still havent gotten my period. Does azithromycin interfere with lutera effectiveness is it possible im pregnant?

Brief Answer:
It may reduce the effectiveness of birth control pills.

Detailed Answer:
Hello dear,
Thanks for trusting hcm about your health care.
I can understand your concerns.
Azithromycin may reduce the effectiveness of lutera birth control pills because it may interfere with it.
But possibility is quite low.
As you used pulled out method also, the chances of pregnancy can be low( but it is not 100% rule out).
So if you missed your period than you should go for a home urine pregnancy test to rule out pregnancy.
Hope it is useful, feel free to ask more questions.
Good luck.
Regards
