I'm 53 and part way through this. Missed about 3 periods last year. Then things went back to normal. But now I've been bleeding heavily for a week, and lightly for a few weeks before that (when my periods are normally 3 days). But, with no period pain, which normally would be very bad. Go figure.
Looking back, I think I had peri symptoms but just didn't recognise them as such. For eg. I had a year of having hot flushes, but it was that hot summer, and I just thought I was hot because of the weather. I had night sweats, but I have a lot of nightmares, so I just put it down to that. Also, not the best sleep for a few years, but again, thought it was just the nightmares. I never once thought back then that I was perimenopausal, and I felt very happy and upbeat the whole time.
I don't get any of that anymore. Apart from the bleeding, I'm really happy, sleeping well, no flushes or night sweats, so I think I'm at the last hurdle.
For those saying "just take HRT", it's really not that simple, because many GP's won't prescribe it. I had a call with my GP this week, to see if she felt I should go on to HRT, main symptoms just being I'm very achy. She said only 15% of women take it, and if possible I should try to avoid it and add supplements to my diet. I'm now taking 20mg Collagen, cod liver oil and vitamins every morning. So far, so good.
Can't wait for the periods to stop, it's going to be great!
