Try not to get down about the 6 that are growing! And try not to compare yourself to the lucky ladies who have huge numbers. (that is still always hard for me!)
This was just your first monitoring appointment. There is definitely a chance that others could catch up. How big were your biggest follicles today? For my last egg retrieval - I think I only had 3 follicles over 10mm on my first monitoring appointment. I felt so disappointed. I did end up having 5 at retrieval day - so a few did catch up. I did stim a couple days longer this time, and then my Dr. added ganrilex to prevent me from ovulating while the others caught up.
Keep us posted on how things are going - and hang in there!
