In the absence of withdrawal bleeding, should I put on a new disc or contact my doctor?

The Nuvaring package leaflet provides guidance on the topic of interest to you: https://www.gdziepolek.pl/produkty/55364/nuvaring-przyrzad/ulotka/109760 If withdrawal bleeding did not occur on time, but you used NuvaRing as directed and did not use other medicines at that time, the likelihood of pregnancy is very low. Continue to use NuvaRing as before. However, if withdrawal bleeding does not occur twice in a row, there is a likelihood of pregnancy. Contact your doctor as soon as possible. Do not wear a new NuvaRing system until your doctor has made sure you are not pregnant. If withdrawal bleeding does not occur during the first break from NuvaRing and you have not used the vaginal treatment system as directed, you may be pregnant. Contact your doctor before taking the new NuvaRing. It is not clear from your entry to what extent you are sure that you used the disc correctly. If you have any doubts, please follow guideline number two. Regardless of the above information, you can also perform a pregnancy test, the result of which will undoubtedly be a guide for you, and may be of interest to the gynecologist if a visit is needed.
