I can agree with the above post. My dr. told me today my progesterone is a little low and quite honestly i have been having thinning hair for a while now ~~ and it's getting worse!
When your progesterone goes down your hair will thin out. Mine has done the same thing...with each m/c. I mentioned it to my doctor and she said it was b/c my progesterone was low...she told me it happened with her pregnancy too.
I am not sure what hormone med that you are taking but I am on clomid and ovidrel and have noticed that I am 'shedding' more so than usual, friends have even commented on it.......
I'm beginning to think maybe there is a connection. I don't know anything for sure. But, you are about the 3rd person that had that happen under the same circumstance. It really sounds like it does cause it.
