"Teen Mom OG" star Amber Portwood is reportedly pregnant with her second child. Amber, who called it quits with her longtime boyfriend, Matt Baier, earlier this year, has moved on to a new relationship with current love Andrew Glennon. They two are said to be welcoming a little bundle of joy in 2018. However, some fans are wondering if Amber's pregnancy was planned, or if it took her by surprise, much like her first pregnancy with daughter Leah.

Amber's pregnancy was 'unexpected'

According to the latest Teen Mom OG news, Amber Portwood is pregnant again with boyfriend Andrew Glennon.

Amber and Andrew met when Portwood was filming "Marriage Boot Camp" with then boyfriend Matt Baier. The two hit it off and quickly entered a relationship. Now they're expecting their first baby together, and Amber tells fans on social media that she's happier than she's ever been and has been focusing on her family. Sources tells Radar Online that Amber's pregnancy with Andrew was not planned, and that the big baby bombshell took her by surprise. The insider went on to reveal that the pregnancy was "totally unexpected," and that Amber has been having a hard time dealing with morning sickness. However, her "spirits have been good" during the pregnancy.

Amber hasn't officially announced pregnancy yet

Amber Portwood's pregnancy hasn't officially been announced to "Teen Mom OG" fans. However, sources say that the reality TV mom has already started telling her close friends and family members. The insider claims that Amber and Andrew began telling people the big news a few weeks ago, and that everyone has had a "good reaction" to the information.

Meanwhile, fans are wondering what Amber's doing about her medication. During a recent episode of the show, Portwood opened up about not getting pregnant with then-boyfriend Matt's baby because she was afraid of the impact her medication for Borderline Personality Disorder may have on the child. The subject may be addressed in an upcoming episode of "TMOG," as the brand new season is set to begin airing later this month on MTV.

Another sibling for Leah

This will be the second child for Amber Portwood and the first for her boyfriend Andrew Glennon. Amber is currently the mother of daughter Leah, 8, whom she shares with ex-fiance, Gary Shirley. Leah is already a big sister to Gary and his wife Kristina's daughter, Emilee, and it looks like she'll be getting another younger sibling in the very near future.
