I have been struggling quite some time now with amenorrhea; the longest I remember going without a period was about 5 months. I’m almost 21 and not overweight. I was told I had no cysts on my ovaries from being seen through ultrasound. My testosterone levels have been high though (along with symptoms of slight hirsutism and acne), progesterone low, and my TSH was . Could this be a thyroid problem or PCOS? I really would like to get to the bottom of this and get back to normal. Doctors were unsure of the problem. How do I regulate ovulation if my body is not doing it naturally and what would cause it to not be doing it?
