Question : I finished my last antibiotic Thursday and my nuvaring came out Saturday as scheduled. I had unprotected sex last night. Should I use Plan B as a back up to insure I don't get pregnant? I'm not sure if the antibiotics would've mess up the levels. Im suppose to start my period this week. Thank you!

Brief Answer:
No there is no need of plan-b.

Detailed Answer:
Hello dear,

Thanks for trusting us about your health care.
I can understand your concern here.
I have gone through your history and in my opinion that there is no need of plan-b because this is one week break period of nuvaring after using it for 3 weeks and there is no chance of pregnancy.
Only two three antibiotics ( like rifampicin and tetracycline) can affect hormonal levels, rest of the antibiotics will not affect the hormonal levels.
So there is no need of plan- b.
Hope it is useful, feel free to discuss more questions.
Good luck.
Regards
