For starters, the embattled reality star is still legally married to another man, but she's pregnant with her boyfriend's baby.
Also, Jenelle recently had an abortion after she and her husband got pregnant, so it hardly seems like the right time to try to start a family.
Still, Jenelle apparently thought that it was...and after dating boyfriend Nathan Griffith for just two months, they decided they wanted to try to start a family of their own together.
Jenelle has a son, Jace, whom she does not currently have custody of and Nathan has a daughter from a previous relationship whom he does not have custody of either.
In this sneak peek of this week's Teen Mom 2, however, we see that Jenelle's pregnancy was definitely planned...even though she had a possible jail sentence hanging over her head.
Check out the clip below and tell us if you think Jenelle is jumping the gun.
