I personally, don't like wondering, and worrying, so going to the doctor's is just something I prefer to do, for myself.

I'm also, not a fan, of trying to self-diagnose myself, either. Amazing, how much is out there, I could have or not have.

2-3 years, is a long time without a period. Are you having other menopause symptoms, that leaves you believing, this is what it could be?

I'm in my late 30's and not even close, it would appear to menopause.

Hope you check back in, let us know, you are ok?
