"We'd like to thank everybody for praying for Michelle," Jim Bob Duggar says in the video, apparently taped at Michelle's bedside at the University of Arkansas for Health Sciences in Little Rock, where she was admitted over the weekend.
"Thank you for all the well wishes we have been receiving," Michelle says. "I am feeling much better. The gallstone has kind of calmed down a little bit, [my] blood pressure is still kind of getting regulated, and the baby sounds good."
A spokesperson for TLC, home to the Duggar's 18 Children and Counting, told PEOPLE Monday that pain from the gallstone had caused Michelle to have early contractions.
But Jim Bob goes on to say in the new video that he is hopeful his wife will get to go home after a few more days of care and carry her child to full term.
18 Kids and Counting airs Tuesday nights at 9 p.m. on TLC.
