Just for women only!!?

Ok, I know ive gotten some answer. But, Im gonna add more to this and need your help ok. Im 34 years old and I haven't had my period since last month between 24-30 and I haven't had one this month. I've had my tubes tied and that's it and also i have been feeling little dizzy and sick at my stomach. I've had my sugar, diabetes and thyroids check so anymore suggestions. People has told me its a sign of early menopause. But, people tells me im to young to have menopause. Please, help me and tell me what you think it is and what I need to do. Thanks
