Actually I forgot there was one other sign.
The one and only time I have ever gone to a psychic was on my birthday the year before DD was born. The psychic had no idea we were TTC. Anyway, one of the things he said (and he said many things that were right) was that my mother (who had passed away) was showing him "many many eggs." He asked if Easter was big in my family, because it didn't make sense to him. It made sense to me months later when my donor gave me 43 eggs/35 of them became embies.
Thanks for posting this Q; it's been really great thinking about it and reading about others and their signs.-Lizzie
