Amber Portwood Confesses The Devastating Reason Why She 'Can't Get Pregnant!'

Does Amber Portwood want another baby?!

In an sneak peek for Teen Mom OG, Amber and her future husband, Matt Baier, discuss the possibility of starting their own family one day. She explained that her ex, Gary Shirley, was asking her when the two plan on getting married and having a baby!

"I just found out that I got re-diagnosed with boarder line personality and bipolar disorder and I've been taking 3 different medications that I will have to take for the rest of my life," she explained. "I can't get pregnant on this medication. I can, but it would mess up the fetus."
