Embryos didn't stick

my Fertilitydoc said she's gonna start me on DHEA when she starts me on birthcontrol, before my next IVF, she didn't want me to be on it a full 3 months though, she said there are side effects like high cholesterol etc. that i don't need to mess with .  she said the women on it for longer usually have premature ovarian aging,, and i don't have that, but since 3 of my embryos degenerated and 2 didn't implant,  it shouldn't hurt to improve egg and embryo quality.. i asked about steroid, hgh, heparin, and she said i don't need that stuff for my history... thank you all so much for your suggestions so i could go into my follow up appt. with more knowledge,, i feel good about that DHEA :) sandy
