Hi!
Everyone is different with regard to the return of menses after removal of the Mirena, so if you were my patient, I would not be terribly concerned. Because you had regular periods previously, you will most likely resume regular cycles again.
If you were my patient, I would repeat the pregnancy test, and if negative, I would offer you a prescription for progesterone to see if we could jump start your cycles.
Hope this is helpful!
Good luck!
Dr B
Thanks so much for your help
