Everything You Need to Know About Pregnancy Acronyms

An obstetrician is sitting at a table across from a woman who is wearing a light blue sweater with her right hand on the side of her face. The doctor is showing the woman an ultrasound picture on a tablet.

I’m sure I’m not alone when I talk about how unprepared I was for all that pregnancy throws at you. Sure, I figured there would be morning sickness and achy boobs after I got my big fat positive test, but other things were surprising…like the insane use of pregnancy acronyms, for example.

While the “gestational journey” is undoubtedly beautiful and amazing, it also comes with a huge learning curve for first-time pregnant folks.  

I still recall hopping onto pregnancy and fertility forums for the first time and being shocked by the wide range of nicknames and abbreviations.

EDD, TWW, HPT, LMP – the list continues.

Now, sure, once we get the hang of what all these cute acronyms stand for, it’s a lovely way of communicating without having to constantly spell out words like human chorionic gonadotropin (hCG.)

Figuring them all out, on the other hand…not so easy. If you’re overwhelmed by the barrage of “secret pregnancy codes,” you’re not alone. 

Before you get too stressed, though, please take comfort that we’ve done the hard work for you. Take a look at this helpful list of the most common pregnancy acronyms you might come across!

Why Do Pregnancy Acronyms Exist in the First Place?

I know what you’re probably thinking – wouldn’t it just be easier to use the regular word for things instead of creating elaborate codes and abbreviations?


But then again, continually talking about basal body temperature, intracytoplasmic sperm injection, or cervical position doesn’t feel natural either…right?

Pregnancy acronyms might seem confusing initially, but they allow online communities of expectant parents to talk more conversationally with each other. We no longer sound like we’re trying to write a doctoral thesis on the pregnancy process. 

Simply put, pregnancy abbreviations are just easier and more casual.
