Hello Doctor, I have missed my period by 15 days (last date of period was March 15, 2014), I have consulted a doctor and she prescribed me gestofit 300 sr . She also did a pregnancy test, which showed a single faint line, so she was doubtful about pregnancy. but as per my belief I have not undergone any sexual intercourse during the concerned period. Please let me know the use of gestofit 300 sr . Will it help me to get my period back as I had regular periods earlier. Also, I would like to inform you that it has been 1 month I have come to a new place with my husband and also have gained 2 kg weight recently. Please help....
