I am taking 1/35 Nortrel for birth control. I just recently switched from my last birth control, which has less hormones, over to Nortrel. I just finished up my 2nd pack, and when it comes time to my period all I get is brown discharge. I thought I might be pregnant so I took multiple tests and they call came back negative, so this month when i missed my period again I took another test and still came back negative. Please help! Can Nortrel stop your period completely?
