Also known as: 妊娠検査, 妊娠検査薬, 验孕棒
A small stick-like object used to determine whether or not a woman is Pregnant, determined by matching (usually) pink lines after a urine sample. Usually two lines means pregnant and one line means not pregnant.
A minor Meme related to pregnancy tests cropped up in late 2014, where a feminine finger pointing to a pregnancy test would be added into existing images. (See post #1824996 and its parent.)
Do not add the Pregnant tag unless the character has a visibly pregnant belly.
