Bristol Palin Reveals Another Disappointing Pregnancy: "Trying To Keep My Chin Up"

Just one month after MStars News learned that Sarah Palin's daughter, Bristol was calling off her marriage to Medal of Honor recipient Dakota Meyer, we have now learned more shocking news ... she's pregnant with her second child!

According to Entertainment Tonight, Palin revealed that she was expecting another child on her blog, and the words that came out of her mouth didn't show that she was too thrilled about being pregnant once again.

"I wanted you guys to be the first to know that I am pregnant," Palin, 24 stated. "Honestly, I've been trying my hardest to keep my chin up on this one."

The daughter of the former Governor of Alaska added, "At the end of the day there's nothing I can't do with God by my side, and I know I am fully capable of handling anything that is put in front of me with dignity and grace."

She continued, "Life moves on no matter what. So no matter how you feel, you get up, get dressed, show up, and never give up. When life gets tough, there is no other option but to get tougher. I know this has been, and will be, a huge disappointment to my family, to my close friends, and to many of you," she admitted.

MStars News previously learned that Palin called off her May, Memorial Day wedding when rumors started to swirl around about Dakota having another wife.

It's unknown if Meyer is the father of her second child. Palin is asking for privacy at this time.

"But please respect Tripp's and my privacy during this time. I do not want any lectures and I do not want any sympathy," she asked. "My little family always has, and always will come first. Tripp, this new baby, and I will all be fine, because God is merciful," she finished.

Bristol has a 6-year-old son, Tripp, who she shares with former fiance Levi Johnston, 25.
