Kim Kardashian also experienced swollen lips during her first pregnancy. She displayed her puffed-up pout on Instagram with the caption, "My pregnancy lips are outta control. #IGuessNotABadProblemToHave."
Jessica Simpson tweeted this photo of her puffed-up lips while pregnant with daughter Maxwell, and said, "Woke up looking like the lip injection fairy visited me in the night! Is this how pregnancy face begins?! Yikes!"
While not a common side effect, many mamas report that they notice occasional lip swelling during pregnancy. Unless it's severe or painful, it's probably nothing to worry about.
