Ward, introduced in the MTV show's third season, is already mother to 17-month-old Noah with husband Brian Finder, but claimed that she is happy about becoming a mother for the second time.
"Yes I'm pregnant again," Ward posted on Facebook this Saturday. "I really do not care if you think it's wrong."
The reality star insisted that she and her husband support Noah without any help from the state.
"I am married, we pay for everything, we aren't living off of family or anything," she continued. "We pay rent, we own our car, for insurance, pay for food, pay for our cell phones, pay for clothes and whatever Noah needs."
Fellow 16 & Pregnant star Markai Durham was the first of the series' original stars to become pregnant for a second time, but eventually opted to have an abortion, in a decision shown on the Dr Drew Pinsky special No Easy Decision last year.
E! Online reports that controversial Teen Mom 2 star Jenelle Evans was one of the first to offer her congratulations to Ward, insisting that the couple are definitely mature enough to have a second child.
The current season of 16 & Pregnant continues May 24 on MTV.
