Thin endometrium- anyone else?

Bee
Just received word from my dr that my ultrasound showed my endometrium at a thickness of 2.4mm. I've read that a thickness of 11mm is required to conceive. So that fucking blows. Anyone else been diagnosed with this problem/ or have experience? Anecdotes? Advise? It's likely caused by low estrogen. So more soy for me I guess.
