In a recent message to fans, the Teen Mom 2 star spoke of a recent visit to her doctor's office, in which she and her fiance, Cole DeBoer, were able to see their child.

Houska announced her pregnancy earlier this month on her recently launched website.

"HELLO EVERYBODY! I’m so excited to finally be launching my website, and I felt like the perfect first post…would be to announce to everyone that baby DeBoer is expected in February 2017!" Houksa revealed to fans on July 13. "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."

"I’ll be sure to keep you updated throughout this pregnancy, and I’m also excited to use this website as another way to stay connected with you all about tons of other topics!" she continued. "I’m so grateful for everyone’s continued support and kind words!"

Houska and DeBoer are set to wed this fall.
