Hi and welcome to MM Jaynie66
The peri stage can result in long gaps between periods - it sounds as though your ovaries are having a final few gasps. It might be worth popping to the GP for reassurance.
If your ‘lady bits' are itchy and sore then some local oestrogen( Vagifem) might be a good idea (ask GP for this) and also some vaginal moisturiser used daily can help to keep the flora balance good and prevent some of the urogenital problems - most of us use SYLK or the YES products. Multi Gyn Actigel is great to treat BV ( itchy and sore) and used a couple of times a week can also help to prevent infections taking hold.
If you get problematic bleeding (so very heavy), then this will need investigating. DG x
