Bristol Palin, daughter of former Alaska Gov. Sarah Palin (R), announced in a blog post Thursday that she is pregnant.

Palin wrote that she shared the news "sooner than I ever expected due to the constant trolls who have nothing better to talk about." Palin wrote that the pregnancy "has been, and will be, a huge disappointment to my family" and asked for privacy.

"Honestly, I’ve been trying my hardest to keep my chin up on this one," Palin wrote. "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."

Palin's verified Twitter account shared a link to the post Thursday:

Palin gave birth to her first son, Tripp Easton Mitchell Johnston, in December 2008. Palin and Tripp's father, Levi Johnston, broke up in August 2010.

Palin was recently engaged to marry Medal of Honor recipient Dakota Meyer, but the wedding did not happen.
