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.
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?

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.

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