It takes 18 months divided by 2
First of all, let’s take a few moments to congratulate this person for correctly doing the math. Two times nine is 18, but that’s not the number of months it takes to carry twins to term. It only takes nine months or so, the same amount of time as carrying a single child.
Even though this post perfectly described how clueless some people are, it’s not the worst pregnancy-related tweet of all time. For that, you’ll have to search for the tweet where someone uploaded a picture of three pregnancy tests and proclaiming that they don’t have enough money to raise three kids.
