Last night's episode of "Teen Mom OG" had two big pregnancy reveals from Maci Bookout and Catelynn Lowell. 

One of the most shocking was from Bookout, who was previously told by her doctor that she might not be able to get pregnant again. After she got that news she stopped using protection with her live-in boyfriend, Taylor McKinney. 

During the episode she had to reveal to her son Bentley, 6, who she had at age 17 with a former boyfriend, that he was going to be a big brother.

Bookout was also pushing for marriage with McKinney for "the sake of my grandparents" since she is going to have two kids with two different men at the ripe age of 23.

Lowell also announced her second pregnancy on the show, which obviously didn't come without its own drama. 

Lowell's fiance, Tyler Baltierra, was urging her to see a nutritionist because she was self-conscious about her weight when she was pregnant with their daughter, Carly. 

Lowell promised she would eat more than just salad during this pregnancy, but Baltierra was still concerned about her health.
