Orrr...they miscalculated O (much more likely).

That having been said I did get preggo once from BD right after I got off my period, so I must've DTD CD 6-7ish or so. I suspect I had to have Oed early, but even if it was several days early, that's still a fairly big cutoff. But we were 20 years old then and yeah totally super human LOL

Thanks for sharing glowbug and welcome!

totally about the moon signs don't even get me started. Like anyone knows the hour of their conception. One of these days when I'm really bored I'm gonna take the mystic methods apart but it's so stupid it gives me chronic facepalm just thinking about it.

I have a different take on the O and O-1 day bump with girl conceptions (which I concur does seem to be the case based on my analysis of studies as well). I believe that reduced fertility and harsher maternal conditions AND poorer sperm health = more girls conceived and since sperm lives a shorter time in harsher conditions (both X and Y) I suspect that people who may not be ABLE to conceive from 2 or 3 days before O, may be more "set" for pink. Thus, they can only get pregnant with attempts that are pretty close to O. And the people who are superhuman and can get pregnant from 4 days before O are probably high sperm health/high maternal conditions couples.

I like your theory. The author of the book was only positing one reason why some studies find more girls conceived on ovulation day. She wasn't actually claiming to know the reason. I love that this site actually references research articles when making swaying suggestions. I have learned so much from reading the articles and forum posts.

To the best of my knowledge, one of my pregnancies was from a single BD 10 days before O. I was 22, and my DH 23. I do think it's possible for sperm to live over a week. Just rare.
