Which anime did the pregnancy test meme come from?
Closest I could get to an answer.

According to knowyourmeme:


  According to archived discussions[1] [2] from the Japanese imageboard site Futaba Channel (2chan), the photoshop meme originally began as a minor fad sometime in the summer of 2014, but it didn’t take off until the blank template image was posted on Twitter[4] by @Gorxxx_[3] on October 15th, 2014."
