Big day tomorrow!

Tomorrow morning is my baseline ultrasound / suppression check. It's when the doctor decides if I get the green light to start stim meds this Saturday. He (or she) will be looking for a thin uterine lining, quiet ovaries (with no major cysts), and a low estrogen level. I can guarantee that my estrogen is low cause I feel very "blah" and I've been getting awful headaches the last few days.
