I don't think I'm peri-menopausal, but am in my forties so could be. My last few periods have been shorter and very heavy on day 2/3 (tampons and maternity pads not lasting very long). The cycle has also shortened by a few days. It also coincides with 1st AZ vaccine and cycle since 2nd jab in the middle of it has just started a week late. It's probably just a vaccine side effect, but wanted to see if these changes start as suddenly as this if peri menopausal? Also, despite the heavy flow, I've found tampons uncomfortable as though I'm "dry" - have never had this issue before. Again, is this a vaccine thing or does it just start feeling like this suddenly when peri menopausal? Apologies if tmi.
