Hi Tidy
I had all those symptoms starting at age 29 and had the FSH test age 32 with a similar result to you (about 8 I think). I then had another test at age 36 which came back at FSH of 32, which suggests it was peri. Your result is low, meaning it doesn't show you're in peri, but that doesn't mean you're not, it just means it didn't show up that day.
However, as MissBoPeep says, there are other reasons you might be feeling like that - eg thyroid, PCOS (I think has some similar symptoms - someone else might correct me on this)
I also had a dismissive reaction from my first doctor. She quite brilliantly told me I was "too young for early menopause"!! this is despite a history of chemo as a teenager and a warning that it could result in early meno. This was on my notes and I pointed it out to her, but she wasn't interested. It was a big deal to me at the time because i was TTC.
I went back to see another doc, who was much more supportive. I then took the decision to go on the pill, because my symptoms were becoming a real problem - particularly night sweats meaning I wasn't sleeping. It really sorted me out, redistributed the fat in the right places! and got my libido back.
Unfortunately last year I had to come off the pill due to high blood pressure, but symptoms now (I'm 38) have really calmed down. I have a period approx every 3 months but it only lasts a day or two with no cramps or anything.
My suggestion is to go back to the doctor, or a different one if necessary, and make sure they test you on the right day (day 3 of your cycle). You'll find loads more info on earlymenopause.com or the daisy network. If you still don't get anywhere and you can't handle the symptoms it's worth considering going on the pill. It acts as a form of HRT and replaces the missing hormones, and overrides your body's cycle so it really does help with symptoms.
If you want to handle it naturally, there are options such as evening primrose oil and other supplements. Loads of info about those on the websites above.
Sorry this has turned into an essay. Didn't know I was such an expert!!
Good luck. xx
