I think that any score above 40 is showing that your ovaries are not producing enough estrogen to maintain your monthly cycle. Which corresponds to your irregular periods. Sounds like you are in the peri-menopause phase. Not considered menopause until you have gone 1 year without a period. I find out my results this week too. I seem to have the opposite problem - two periods a month!

Don't think FSH/cancer is related at all. But I am not a doctor.

Try meditation in the mornings or yoga to calm your body down. Anxiety can be a symptom of hormonal imbalance.

You are not alone. I wish you well. Good luck with your doctor and keep up posted on what you are doing to feel better.

I am also 42 and my fsh levels in February were 76. My gyno told me that I was definitely in menopause and would more than likely no longer have a period except for maybe once every few months

Well, guess what - I continued throughout the rest of this year having a period every single month like clock-work! The only time I went for an extended time without one was from June to July when I was going through a very stressful time and lost a lot of weight because I could hardly eat at all.

I know this doesn't really answer your question. I just wanted to share my experience to point out that these levels apparently swing quite wildly. I was never retested and I am not very happy with my doctor. I have been having symptoms of menopause.

sounds like you are perimenopausal which is getting into menopause. I am the same age and my FSH is higher and 40 at the age of 32. I haven't had it checked in a while since I am not a candidate for children (Checked my ovaries-they don't produce eggs properly). Your heart racing sounds like an anxiety attack but is common with changes in hormone levels too. I was prescribed a low dose of anxiety medication just to help with that temporarily. I also had to find out what I could do to help them from coming on. Cognative therapy helped a bunch. I didn't realize how freeing it can be to talk to someone without worrying about how they felt about what I had to say, but that is just what helped me.
I have night sweats and depression due to the hormone change. I believe that most of the symptoms subside after your body has stopped bleeding for one year (then is when they consider it menopause).
I told one of the nurses one day that I was menopausal and she bluntly said "oh, so you have gone a year without a period?" I said "No, I am infertile and my FSH lvl is high, but I am going through the change." She says "then you are perimenopausal and not menopausal."
She was quite snotty about it and I was not in a good mood so she was quite lucky I didn't reach across the counter at her! LOL I am sure the look on my face was priceless...I never use the "c" word and I barely kept from it that day. I was bleeding heavily and cramping like a madwoman. I just hope she has more tact with others.

My FHS score was 56, and the obgyn said I should really have no period any more, but I still have one usually once a month, but the last two month it was all skrewed up. I hope this is over soon, because you think you are done with that monthly crap and then it shows up again.
