With Jessa Duggar pregnant with her second child, fans of the TLC show "Counting On" are now looking at her elder sister Jill to see if she's expecting as well. After all, the Christian sisters did say during the season 1 finale of their show that they are planning to get pregnant at the same time.

However, it seems like now is not yet the right time for Jill to be expecting. A fan (@susanbenoit4) asked Jill's husband Derick Dillard on his Twitter account (@derick4Him) if Jill is pregnant again. But Dillard simply replied, "Not yet."

Their decision to hold off their second pregnancy might have something to do with the dangers posed by their family ministry in Central America.

"It's risky here — we stand out as Americans, so definitely we're higher risk," Jill said during the Aug. 30 episode of the show, according to Us Magazine. "You have to talk about things that probably a lot of couples wouldn't talk about back in the States."

With the number of crimes happening in El Salvador, the Dillard couple have to figure out what they will do should something bad happen to one of them. As difficult as those grim conversations might be, Jill and Derick are hanging tough for the sake of their family.

"We've been married almost two years — we have a little baby [Israel David]," Jill said. "If we were back in the States, we wouldn't be talking about, 'Now if you die, what am I supposed to do from there? If you don't come home after you are supposed to [at] this hour, then what do I do?' It's hard to talk about those things, but it's also good for us to [know] like, if something happened, what I'm supposed to do."
