I'm 22 years old and I started taking levo last July. I started with 25 mcg. Since then, I only had one period, and it was three weeks late - back in August. I haven't had a period for almost three months now. My doctor was surprised that I don't get my periods anymore and said that wasn't supposed to happen. She didn't say if I should see a gynecologist to get pills for inducing period, or anything of the sort. She only said to wait a while now since I get a new dosage (25 mcg one day, 50 mcg the other) and have my sex hormones tested again. What should I do??
