Hello I am 33 years female married. I had my last periods on 18th July 2018 in evening. But till date I have not got my periods. As far sexual activity is concerned, the last time was in July 4-5th 2018 only. And after that no sexual intercourse has happened. And to mention that after the sexual intercourse I got my periods on the 18th July 2018 evening as mentioned. After that we did not had any sexual intercourse till date as my husband is out of town. Now I do not have any signs of pregnancy nor I have taken any test at home. So why I am getting delayed in my periods? One more thing to mention I am having lot of pain in both sides of nech as if muscle spasms since a week and for that I consulted doctor and he prescribed my muscle relaxant for a week but I have stopped taking the medicine as I think this could also cause a delay in arrival of periods. Kindly help as to what should be done to get my periods as early as possible.
