yes, it's probably menopause or the new term perimenopause that proceeds before menopause. If you're not having difficulties that you can't handle I suggest that you don't need to see a doctor. Even when you see a doctor, it can be your gp.
I never did see a doctor specifically about menopause until I was feeling so cranky I was having difficulty at work. This was years ago and I started on hormone replacement therapy. I didn't notice a difference taking it but I was able to tell my supervisor I was going thru menopause and both of us were more careful about what we said. lol I figure I "trained" him for his wife. lol
I suggest you go to the library and check out some books on menopause. When you know what to expect you'll feel less anxious.
