Pregnancy Acronyms Decoded

Congratulations! You're pregnant! You've either graduated from the class of Trying to Conceive or you skipped a grade and got your "Oops" diploma. Either way, you're about to be a mom. 

Before you dive headfirst into the pool of learning-everything-you-should-know-about-pregnancy-and-parenting (and those are deep waters), you may want to hold onto that diving board a minute longer. What you may not have expected is the Pregnancy as a Second Language prerequisite.

Early onset excitement is a common side effect of those solid pink lines, but perusing a few mom-to-be message boards will leave you scratching your head if you're not familiar with the lingo.
