I am 33 years old. I get regular periods with 28-30 days gap. I get leg pain usually 1 to 2 days before periods which gives an indication. My last period started on 2.2.13. This month I did not get periods till date. When consulted a nearby gynecologist on 6.3.13, she tested pregnancy test and told that test is negative. For getting periods she prescribed Cycloreg tablet for 5 days. But till date I did not get periods. I am feeling very weak with severe leg pains and vomiting sensation sometimes. Kindly advise.
