Tips for dealing with annoying questions over Christmas?

Hi ladies,

I’m kind of dreading seeing my husband’s family for Christmas— they are lovely people but very Catholic, traditional folks who live in a tiny town in the south. I know the “when are you gonna have babies?” question is gonna happen, probably a lot, and I don’t know how to respond. We’ve been trying for 5 month, which might not seem like a long time, but it’s been stressful and emotionally draining nonetheless. Part of me wants to say, “oh we’re trying! Full of semen as we speak!” to shut them up lol but that’d be a little too much haha. What are your tips for those annoying and invasive questions?
