Had cin2 cervical cancer surgery two weeks ago, had no leaking fluids, had my period last week, i've got brownish liquid all the time. is this normal?

Please call your gyn: #1 u did not have cervical cancer- you had cervical pre-cancer cin-2 #2 your gyn should have told you what to expect post-op and if you are worried please call your gyn, your gyn should have explained that you will get a discharge post op and can last 2-4 weeks but if you were my pt i would check you in the office to make sure no problems, depends how profuse and odorous discharge is.
