In the last few years my periods settled down to a normal 28 day pattern, but the last 3 months it has been more like 35 days, but getting longer and longer between each one. I can't even work out when I am due on anymore, my last one was either 27th or 30th Sept - how do I keep track? I had a very small bleed about when I was due on (I think I was due on anyway) and then it went away again - was that maybe it for the month?
