I started temping this month and was going to start using OPKs too. DH knew I was doing it, but didn't ask questions. Yesterday he asked questions. He thinks I'm being foolish. And he's scared we'll only have sex on peak days if I track. So he's VERY against tracking. The way he sees it, if I want a baby then I should just have sex more. And, if it takes several months of trying, well then good because that means even more sex. He's not a complete sex addict or anything, he just says that's the "natural" way for a married couple to have kids when God wants them to. (Not to start a religious war, but God also blessed humans with intelligence, and our God given intelligence allows us to invent things like thermometers and OPKs, so TECHNICALLY I could say that God gave us tracking, lol.)
So I guess I'm back to going crazy and no tracking. Temping officially lasted 7 days. I could probably sneak in OPKs if I really wanted, but I hate to lie to him. I might try BDing every other day midcycle, maybe between cycle days 8-20, but I think he'll notice the pattern and be grumpy.
