They might not even be engaged yet, but it looks like Jessa Duggar and her boyfriend Ben Seewald are taking a huge step in their relationship. The 19 Kids and Counting star is going on an overseas trip with Seewald, with many guessing that the two might be alone and without a chaperone for the first time.

Seewald shared a photo of the two holding their U.S. passports on his Instagram account with the caption: "Headed out for a Central American missions trip! 12 days, 3 countries. Please pray for our team!"

Duggar and Seewald first started dating back in September. According to sources, the couple take their courtship very seriously, as they are only allowed to side-hug with kissing or any other physical contact off-limits. The couple have been on dates, but only when a chaperone is present.

Meanwhile, Duggar's sister Jill Duggar, who recently married her fiancé Derick Dillard, is enjoying her new life as a married woman.

The newlywed couple, who just celebrated their honeymoon in North Carolina together, are enjoying life as a married couple and are in no hurry to add to their family any time soon.

But as far as babies, it looks like Jill and Dillard are in no hurry as they're enjoying dinners "for two" now -- and that's it.

"I love to cook and have been able to do a lot of cooking," Jill said. "Cooking for two people is a learning experience in and of it self."

Jill and Dillard married in front of 1,000 guests at the Cross Church in Springdale, Ark. last month. Jessa and Seewald are yet to announce their engagement.
