Hi, I Am Woman 37 Years Old. I Am Still

Hi, I am woman 37 years old. I am still struggling to get pregnant. We planned to get a baby by IVF. One week before my menstruation cycle on 15th March 2016, I got an injection of Gonapeptyl 3.75 and the doctor advice me to come again after my cycle finished on 29th March 2016. I got my cycle on 21st March 2016, and I went to the doctor on 29th march 2016 but I were not lucky because the doctor wont come back to this country (UAE), then we decided to meet another doctor. The new doctor adviced me to come back once I got my next cycle without any treatments and medications, but until now I never get my menstruation cycle. Since once month ago till now I fell pain on all of my body and joints, headache, and nausea. Please advice what should I do? Thank you in advance.
