Husband doesn't want to "try" for baby.

My hubby and I are trying to convince our second child but in a weird way I guess?- he doesn't actually want to "try" like planning sex on days that I'm ovulating. He wants to just go on as usual and if we get pregnant then great, it was meant to be. Does anyone else's husband's feel this way? He wants a second child (I was fine with just our little boy) but is acting like I'll just get pregnant this month no matter what.
