Ok so on day 2 of period - started using a menstrual cup last month, as a) environmentally better, b) periods have been either really heavy or light, and thought it would show the blood loss better. Last month was a doddle, cup hardly filled up to the quarter or half point and only changed it every 12 hours. This month, I've bled over 175ml over 2 days. Every cup's been full, or overflowing, and I'm changing it every 2-4 hours. This must be perimenopause, right? (I'm 44, btw). Would you be worried by it?
