So sorry for your loss. Hugs!!
The only thing I have read on this said that your brain releases some sort of chemical between CD11 and CD16 (I think those are the days), and that it makes the egg better suited to divide properly. So, if you ovulate between CD11 and CD16, it is exposed to this chemical making it more suitable for a healthy pregnancy. I think it is an opinion that has not been widely accepted or we would hear about it more, right?? I don't know, I never know who to believe, this doctor or that doctor??
If you talk to your doc about it, will you please let us know what they say? Ever since I read that, I have been curious if there is any truth to it or if it just a bunch of hooey.
