Bristol Palin Shares Snap of Her Tiny Baby Bump

The 24-year-old expectant mom shared the snap to her Instagram page last week as she celebrated her six-year work anniversary.

Bristol Palin has introduced her fans to her growing baby bump.

The 24-year-old expectant mom shared the snap to her Instagram page last week as she celebrated a six-year work anniversary - and her tiny bimp could be seen beneath her medical assistant's uniform.

Two years ago, she revealed in a blog on ABC's website that she travels an hour to work at a dermatologist's office in Anchorage, Alaska.

Palin announced that she was pregnant with her second child in June - just one month after breaking off her engagement to Medal of Honor recipient Dakota Meyer.

She took to her blog to share the news, writing: “I wanted you guys to be the first to know that I am pregnant. Honestly, I’ve been trying my hardest to keep my chin up on this one.”

She went on: "I know this has been, and will be, a huge disappointment to my family, to my close friends, and to many of you...I do not want any lectures and I do not want any sympathy."

But in a second post, she said that the pregnancy had been planned.

“I do not regret this baby," she said.

Bristol first made headlines back in 2008 when she got pregnant at the age of 17 during her mother Sarah Palin’s bid for Vice President.

She gave birth to a son, Tripp, and got engaged to the boy's father, Levi Johnston, but the two never married and had a nasty breakup. On July 4, she shared a picture of her with Tripp, now six.

She has also preached abstinence in the past.

In 2009, she vowed to InTouch that she would not have sex again before marriage and said: "I'm not going to have sex until I'm married. I can guarantee it."
