Hello Doctor, I am 19 years old. My periods were usually regular, but I have not had my period for the last two months. I have not noticed any other symptoms. Pregnancy is not possible in my case. I am concerned about why my periods have stopped and would like your advice on the possible causes. Please guide me on whether I need any tests, such as
thyroid or hormone tests, or an ultrasound, and what steps I should take to get my periods back to normal. Thank you.
