I'm confused ,nothing new there :)
I was under the impression that progesterone is needed to maintain a pregnancy! So how does giving norethisterone ( strong progesterone ) induce a bleed ? :-\
I have tried to read so much I'm tying myself in knots with it all ! I know my own hormones now should be very depleted at 55 so why should they be more up and down then they were when I was 49 ? Surely they should just be lower but more stable ! I'm a bit embarrassed that I'm so ignorant. And the more I read all the web articles the more confused I am :-\

Progesterone changes the lining from proliferation where the cells are just dividing and increasing and growing, to a 'secretory' phase, where the nature of the tissue changes to make it suitable for implantation. This never seems to be explained properly in biology lessons, so I am not sure what exactly it means.
A period comes after the hormone levels drop rapidly, so it is the withdrawal of the progesterone that causes the bleed.
Hope this helps.
It is confusing :o

Can't help with the progesterone bit Dazned but can certainly empathise with the confusion!

Me too! It hurts my brain!!

Also, I have just read that as you get past day 21 (optimal day for implantation), then the continuing progesterone changes the lining in ways that prepare it for shedding. (decidualisation????????? ::) )

Well at least it's not just me then that's a bit confused ! ;D Feel a bit better now !
Ah that explains it DG thanks it's the sudden drop of progesterone that causes the bleed makes sense now SIMPLES ;)
I do like things to make sense in my head it's how I 've always been that way :) I was that awful child that kept on " but why Mum " ;D

Decidulisation ! Isn't that what trees do ,drop their leaves!!! :rofl:
