can someone explain this to me?

First of all to accurately time O+12 you have to know exactly when ovulation will occur. Abstain from sex for 7 days or more, and then have sex 12 or so hours after you ovulate. This has better success than cut off.

That will sway for a boy then I assume?

[Lisap2008]

No O+12 sways girl. for a boy you would want to BD on or as near ovulation as possible.

how do you pinpoint O down to the hour? I chart, but that doesn't really tell me when during the day I O'ed.

I am not fond of OPK's too much money and PCOS leads to wonky results.

[ChicaChels]

okay thats what confuses me....and when i kept reading o+12 sways pink i was so confused....if you it was past ovulation, and the boy swimmers are faster, wouldnt waiting 12 hours give the boys a better chance?

[Lisap2008]

NO because for O + 12 your BDing 12 hours after ovulation has occured ( so about 36 - 40 hours after a + opk )at that time your CM will have started to turned back to creamy and your PH will have lowered which gives the X sperm a advantage over the y sperm.

Y sperm cannot live in anything but wet/ EWCM. for TTC a boy you want to BD on either the day of your + opk or on ovulation day which would be about 12-24 hours after the + opk.

and actually both X and Y sperm swim the same speed. the only difference is X sperm can live in a low PH and Y sperm cannot. which is why I have 4 girls.

if your not using OPKs you can go by CM and as soon as it starts turning creamy again and your cervix hardens a bit you know you have ovulated.

for my 4 girls I did none of this timing we actually conceived them on ovulation but the difference was my PH has always been a 4-5.
