I don't wish to make you depressed but if you are going to be like me then perimeno which for started about your age was all about very weird bleeding patterns. I could go up to 3 months period free and then I would spot for up to 6 weeks and then have a period from hell lasting up to 8 days, this was flooding on a grand scale. I had endless investigations and I was told that my oestrogen dominence was causing the womb lining to build up in the no bleed/spotting time and then the massive bleeds were my body getting rid of it all which is did as I had a ultrasound the day after a massive bleed session had ended and my lining was very thin so nature was doing its job!
It freaked me out big time as I was always convinced something nasty was happening hence all the tests but it was just natural peri menopause.
I then got longer between periods and periods just lasting a couple of days and very slight before they stopped completely.
My friend who had the same could not put up with it and she had the mirena coil fitted and this cured it for her.
Just realised I am not exactly reassuring you other than what you are describing is completely normal in perimenopause.
