My understanding is that estrogen decreases gradually for every woman after the age of 25 or so but that in most cases the decrease is imperceptible/insignificant until one turns 40. After that, it looks like the luck the draw. Some women are ovulating and able to bear children into their mid fifties. Others go into menopause in their late 30s and stop ovulating by 45.
I am 47 and like you I think of older women who are not going through menopause yet and I think "It isn't fair!" I also feel a little tricked because I had expected the change to come more gradually, and I am suddenly afraid.
I didn't want any more children, but I am also sad that I can't have any more. At the same time, I have done my arithmetic. If I were to have a child today, I would be retirement age before the child was old enough for college. Clearly, it is wise of nature to make it difficult for older women to conceive. At the same time, it seems very inconsiderate of nature to give us hot flashes, irregular periods and all the other inconveniences instead of just letting the ovaries close down and letting us go merrily about the business of enjoying the next thirty or forty years of our lives.
Hi Sally...my periods were disgustingly regular too
Every 28 days. I could set a clock by them.
I was around your age when they started getting a little strange (I will be 50 in Oct). When it first dawned on me that I might be going through perimenopause, I felt very very sad. Didn't want any more children, but felt like I was "less than a woman" because I probably could no longer have them. Actually, I hadn't used birth control since my last child was born in 1974 and nothing ever happened...perhaps I was starting to be anovulatory even back then.
But anyway....I felt the same as you. It made me sad to think that I would no longer have a period someday. It meant (to me) the loss of my femininity.
And then....
I started getting the clots and the flooding and all the rest of the icky stuff and I changed my mind fast, let me tell you! ;)
Now I can't wait for it all to end... yippeeee!!!!
Hope your transition is a pleasant one...
