Hi Sarah,
Thanks for writing in.
Since
Cerazette has
desogestrel , it can cause quite a few bleeding abnormalities. Usually, the bleeding becomes more infrequent as the time a person stays on this drug increases. As in your case, since the bleeding is getting prolonged, I would suggest you speak with your physician about switching you to another
contraceptive.
I would also suggest that an
ultrasound of the pelvis be done to rule out any other disease process that we may be missing.
Hope this helps
Regards
