Thanks Sarah for repsonding. I hoped you'd chime in. I really don't know if I ovulated or not. I did have a + OPK and a dip and rise in my BBT but that may not mean anything. The RE told me he thought based on the condition of my endometrium that I had ovulated 1-2 days prior to the ultrasound which was performed on Day 16. I don't have progesterone or E2 levels to back up or dismiss ovulation. I did not have any stims that cycle. It was a preliminary exam. Just trying to make heads or tails out of the ultrasound so I can ask my RE the right questions. Mainly, my follicle count and the lining thickness and how it may affect my success with IVF.
