More frequent periods, emotional changes in 35 year old = perimenopause?

I'm 35 years old. In my teen years, all thru my 20s and into my 30s, I got my period every 34-38 days, approx. I know that's MUCH longer than "average", but it was normal for me because it was very consistent. (I don't use birth control pills).

However, in the last year or so, I've noticed I'm now getting my periods every 30-34 days, approximately. There are some a bit longer, but overall I've definitely sensed a "shortening" in my cycle. Does this sound more like a change that occurs 鈥渏ust because,鈥?or a change signalling perimenopause? Don鈥檛 worry: if anything extreme or unsettling starts happening, I'll of course see my ob/gyn.

Also, I've clearly sensed in the last year or so that my ADHD, forgetfulness, anxiety and insomnia issues (which I've always had to a mild degree) have gotten worse. My psychiatrist even thinks I have a bit of depression now as well! I've heard that ALL of the above can also be symptoms of the hormonal changes of perimenopause.

Your thoughts? Thanks! :)

OOPS! Sorry, I forgot to explain perimenopause, although if you're answering this question you probably already know. :) Anyhoo, per the Mayo Clinic website, perimenopause...

"...marks the interval in which your body begins its transition into menopause. Perimenopause encompasses the years leading up to menopause -- anywhere from two to eight years... The levels of your reproductive hormones -- estrogen and progesterone -- rise and fall unevenly during perimenopause. Your menstrual cycles may lengthen or shorten, and you begin having menstrual cycles in which you don't ovulate."

It could be a sign, yes.

Any changes in your periods, emotional changes, forgetfulness usually are signs of perimenopause.

See a Gyn who will give you a blood test to check your hormone levels.

I dont think this is necessarily any type of menopause but I am not GYN.
Have you ever had children? It is very likely that your cycle is just changing
