Hello,I'm new here, but like everyone else, been through hell, hoping, and looking for answers! I'm 36 and just had my first embryo transfer this past Monday, 7/13. Today, day 4 after the transfer, the doc's office called that my estrogen level from yesterday's blood work was a "little lower then we'd like it to be" 97, and progesterone 20+. He's starting my on estrace today.
