Title: confused as usual !
Post by: dazned on March 05, 2015, 11:03:44 AM
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

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
