Ovulating but Amennorhea(amenorrhea)?

Ovulating but Amennorhea (amenorrhea)?

I haven't had a period in SEVEN YEARS.  was on the pill for 17 years. Stopped about 6 months ago.

went to see a reproductive specialist.  She did a vaginal ultrasound. She said everything, including my uterine lining, looked normal.  she said it looked like I ovulated, I have eggs, etc. She expected it would be too thick or too thin after not having had a period for so long, but it looked normal.  They did blood tests, which said I did ovulate.  And, she said she expected I'd get my period within a week.

So what happened?

Same thing that happened the last 4 months- 2 days of cramps.. and NOTHING.  Just a little white, milky discharge.

Anyone have any idea what is wrong with me?  Help?

They did a progestin challenge test 2 months ago which I failed.

Now, I'm going to have to do that, again.

And, when/if that fails, I'll have to do a ESt then progesting.

I am SO frustrated.  34, running out of fertility time!

Anyone have any ideas?  Help please?
