Re: How long is your luteal phase?
My DH never knows if or when I test, unless it's positive. I stock up on Dollar Store tests when I know pregnancy is a possibility, and just test once every few days if I think AF is late. This is generally while I'm nursing, so I don't know what my cycle is doing. If I'm past about 30 days from my last period, then I start testing.
Maybe if you have a bunch of cheap tests, and don't bother saying anything to him about it (not to be sneaky - just so he doesn't have to stress) then he wouldn't mind?
DH married for almost 14 years, parents to 7 small people, so far.
