Hi Lulu - what you describe is typical of the years leading up to menopause which is when your ovaries begin to fail and your oestrogen level begins to drop. It all sounds "normal" to me. Monthly cycles can vary hugely in length and timing between them. You may miss quite a few then have a few months when you get a period right on time. The longest I went between periods was eleven months then I went back to a fairly regular cycle. You may have long periods or short ones, light or heavy. You should not have bleeding after sex though - that is one thing that has to be reported to your GP.
As your oestrogen level drops then more symptoms can turn up (delightful) and sweating/hot flushes is one of them. You might also experience vaginal dryness/pain or urinary infections. This is because the lack of oestrogen leads to thinning of the tissues so they are more easily damaged and germs from the back passage are more easily able to be transferred to the vagina. Sometimes you get the feeling that you have cystitis but there is no infection when your urine is tested. Vaginal symptoms do need discussing with your GP as they don't get better on their own. Topical oestrogen is usually necessary either in the form of a pessary or cream.
There is lots of information on this site so keep reading and posting! Sorry if this is a bit disjointed but I'm on my phone not the laptop and haven't got my specs on
