Hi all, After a successful fresh IVF cycle in 2018, I am back for another journey in hopes for baby #2. I have 2 frozen embies and I have opted to do a natural thaw cycle as I have fairly regular cycles. However, after a good scan on CD9 (9mm embryo on right side and 10mm on left side), my left embryo decided to shrink and my right embryo was only 11.5mm today (CD12). I go back for another scan on CD14 in hopes that I can trigger soon but 11.5mm on CD12 seems too small for my cycle length (28 days). Has anyone experienced something similar? Is this a sign that this cycle may be a flop? Thanks in advance!!
