I am 40 years old now but 3 years ago I had an endo ablation because I was having severe pain and erratic bleeding with my periods. Since then I have not had a period and it has been a heaven sent - no period = no pain. Before the ablation I was having severe hot flashes at random times, night sweats, insomnia, headaches, low labido and mood swings. I was beginning to suspect that I was entering an early menopause. But since the ablation, those symptoms have disappeared except the night sweats and insomnia - these are much more milder though. With the already lack of a menstrual cycle, how would I know when I hit menopause?
