TTC Abbreviations & Acronyms

Alright ladies, if you’re new to the online world of TTC, you’ve most likely encountered a few BFNs, BFPs, and some agonizingly long TWWs in the forums you’ve visited.

In my opinion, TTC abbreviations are a sort of universal language for those of us that dive headfirst into the TTC world. It’s a “secret” language full of acronyms that bond us all together during one of the most trying times of our lives, the journey to getting pregnant.

Now beyond learning the “basics” of trying to conceive you are also hit in the face with a ton of confusing TTC abbreviations. I myself find it easier to just throw in a “DPO” in a post rather than spend the extra two seconds writing out “days past ovulation”.

I can’t tell you how many weird looks I’ve gotten while in a direct conversation with someone when I ask what CD they are on, or if they used FMU to take their pregnancy test.

I always know instantly when someone has no idea what I am talking about.

It’s that moment of pause….That quizzical expression on their face looking at me like “Did she just say FU to me??”


Which in return leaves me standing there stammering, while I try and vomit my next sentence out to assure them I most certainly did not direct them to go F themselves!

Eh, SORRY, that’s a TTC abbreviation it means first-morning urine!”

The good news for you is that most of the TTC acronyms are easy to decipher.

So don’t fret, once you learn the lingo you’ll be jumping into the convo in no time. Before you know it you’ll be talking in TTC abbreviations with friends and family (enjoy the puzzled looks!).

That is when you really know you’re TTC obsessed, and there’s nothing wrong with that!

Below you will find some of the most popular TTC abbreviations that I use on P is for Pregnant as well as a loooong Master list of all the acronyms that I know from my many, many years in trying to conceive forums.
