Chelsea Houska has officially entered her second trimester. The pregnant “Teen Mom 2” star shared an update on her progress on her blog late Wednesday, telling MTV viewers her upcoming bundle of joy is now the “size of a lemon.”

“My belly hasn’t grown yet but my boobs are legit the size of Texas. So that’s fun lol,” she wrote. “I’ve been starting to have more energy and trying to get healthy and get back in the gym, so I’m feelin goooood.”

The 24-year-old reality star said she recently saw her midwife who told her baby No. 2 is looking “great” and gave her a new sonogram picture, which she shared with fans. “She even showed us our little nugget,” Chelsea gushed. “So exciting!”

Chelsea also shared a second quick pregnancy update on Twitter Wednesday, revealing to her followers she’s planning to have an all-natural birth. “I’ve been reading a lot about hypnobirthing,” she told one fan, adding she’s planning to deliver in hospital. “I’m too nervous to do that!” she wrote when a follower asked if she was having a home birth. 

While Chelsea has been open about her second pregnancy since announcing it last month, she hasn’t revealed if she and husband-to-be Cole DeBoer will be welcoming a baby girl or boy. She has, however, made no qualms about revealing her 6-year-old daughter Aubree, whom she shares with ex-boyfriend Adam Lind, wants a sister.

“We are beyond excited for this journey and can’t wait to share it with you all! Big sister Aubree is also extremely excited and it’s no secret that she is hoping for a girl haha,” Chelsea wrote in a July 12 blog post.

A new baby isn’t the only thing on the horizon for the “Teen Mom 2” star. She and Cole are also just weeks away from their wedding date. The couple are reportedly tying the knot on Oct. 1 in South Dakota.
