Hi, I'm a 20 years old female who has been suffering from the absence of menstruation for approximately 4 months, the last time i had my period was in 26 June. I'm single and there ain't no sexual intercourses AT ALL, im a virgin. There ain't no specific reason, but I think it might be related to the change of my eating habits, since I suddenly lost 4 kilos and I'm now 50kg, 170cm. I heard about Amenorrhea, do I have it right now? by the way recently i feel a veryyyy mild abdominal pain n my vaginal fluid is thick n increased in execretion. what shall I do?
