I have also tried the 100 X 12 days a few times over the last 3 years & I always end up bleeding anywhere from day 7 to day 10
I have never managed the full 12 days without a bleed so now I alternate with 100 days 1-3 then 200, 100, 200 & so on & I find this works really well for me & I have my bleed at the usual 3/4 days after finishing the course. I also go roughly every 6 weeks. I'm 57 & almost 5 year's post meno. Due to an upcoming long holiday I was planning on going 7 & half weeks between cycles, can anyone advise if this would be okay?
