While it may seem like timing sways, it doesn't. Really the best time to conceive is O-3, O-2, O-1 and to a lesser extent O day. If you're DTD on O-3 only, then that's swaying pink because it leaves one attempt in the fertile window AND because it's a few days out from ovulation, not as many sperm remain which sways pink as well. It seems like fewer sperm equals more girls but not always of course because there's always exceptions. There have been so many Shettles opposites that I have a hard time believing in it. O-3 does cut odds of conception more so than BD at pos. Opk which is what Atomic suggests since she wants best odds of pregnancy so we're not swaying for ages. I will say though that I did get pregnant with a 3 day cutoff first month TTC while swaying but baby didn't stick. I have a friend who had a 2 day cutoff and is about to have her daughter so I think it's more of it being number of attempts rather than the actual day. Of course if you want to include timing that's completely up to you. We all have to tweak our sways to suit us our own individual circumstances. :)
The advanced opks drive me bonkers. lol I'll get several days of high readings which is totally normal so don't worry if that's what happening. Clearblue says it's fine to get up to 8 before getting a peak reading. I do use that kind but I find the cheapie OPK sticks or the regular digital ones are easier.
Good luck! :)
