Hi I Have Been Prescribed Ovares Sr 75 Mg Since

Hi

I have been prescribed ovares sr 75 mg since my AMH level is low. I have been taking this medicine for last 6 months. Though initially I was taking Ovares 25 mg three times a day and now 75 mg once a day since last three months. My periods are always regular. This time however they are yet to come. My last period was on 13th Feb 2016. I have taken home urine pregnancy test and it came out negative. What should I do now? I have stopped taking ovares from 14th March 2016 and still I have no periods to today. Please suggest.
