Jessa Seewald's pregnancy journey has just begun, but she can rely on her mother and sister, Jill Dillard, for plenty of advice on what to expect while she is expecting.

Dillard in particular adds an increased level of knowledge because of her midwifery education.

"[Jill] has all the knowledge and training," Jessa told PEOPLE on Thursday.

Training and preparation is key, but, as Jill's own delivery showed, one cannot plan for everything.

After preparing for a natural, home birth on or around March 27, Jill and her husband, Derick, welcomed baby Israel David via C-section on April 6 in a hospital.

"I am not comparing, not worrying about what could happen, we are just getting prepared," Jessa said of Jill's 70-hour labour and delivery.

"Every birth story is unique. We think we want to go with a midwife and plan for a home birth, but I want to just be prepared that not everything may go as planned and try not to get too worried about it."

Jessa and her husband Ben announced on Tuesday that she is entering the second trimester. The 22-year-old mum-to-be said she is grateful that her morning sickness has passed.

"I thought I'd crave pickles and lemons because my mother did, but I couldn't stand them," she shared. "And one day I suddenly couldn't do dairy. I would sit in bed and eat crackers, hoping the nausea would pass."

She said her 19-year-old husband was doting during those trying times.

"He's so sweet," Jessa beamed. "[He's been] waiting on me hand and foot."

Jessa and Ben married on November 1, and "19 Kids & Counting" fans eagerly awaited her pregnancy announcement. The reality show airs on Tuesdays at 9 p.m. ET on TLC.
