Your Dictionary for Trying To Conceive-Acronyms

Newbie in the TTC community? Waiting for that HAH? Can’t believe AF arrived again?

If you have no idea what these abbreviations mean, and you’re wondering about the weird hashtags and abbreviations you see others use in different forums online you’ve come to the right place. While browsing fertility forums or social media channels about pregnancy journeys, you most likely have already come across sentences like this: “I’m in my TWW, couldn’t take another AF, OPK helped a lot this time, lots of BD…” and especially if you’re new to this world, this jargon can be quite confusing.

Trying to conceive can be a tough challenge for some, and while trying to get pregnant it’s certain that you learn a lot about your body, your hormones and which vitamins (such as folic acid) you should take. What comes as a surprise to many, is that one might also need to learn the jargon and abbreviations used by the growing TTC community on social media. But don’t worry: the Pearl Team has put together the ultimate “ttc-dictionary” to chronologically guide you through the world of the online TTC community.

Let’s start simple: you and your partner decided you want to become parents, congratulations! From now on you are on your TTC journey:

TTC- Trying To Conceive

Contrary to common belief, one might not get pregnant right after coming off of the pill or as soon as you started trying regardless of birth control. It’s a lot more common than not, that couples are trying for some time before the woman actually gets pregnant - how long depends on different factors.

After age 35, fertility starts to decrease (age related infertility), but also factors like potential health problems, your lifestyle, and genetics can have an impact on your fertility. So let’s start to get to the bottom of the TTC language:

BC- Birth control or before children BCP- Birth Control Pills, The Pill

The first choice when it comes to contraception is still the birth control pill. After stopping it, it takes roughly three to six or more for the menstrual cycle to get back to normal, regular cycles.

YTC- Yearning To Conceive

BMS- Baby Making Sex

BD- Baby Dancing (Sex)

DTD- Do/Did The Deed (Sex)

Probably the most fun part while TTC. By having sex during your fertile window, you increase your chances of conception drastically.

DH- Dear Husband

DF- Dear Fiancé

SO- Significant Other

DB- Dear or darling boyfriend

BF- Boyfriend

DP-Dear Partner

Let's not forget the significant others playing a huge role on the journey to pregnancy!

BOB- Baby On The Brain, Baby Obsessed Brain

Starting to see babies everywhere you go? Don’t worry, you’re not alone.

C- Cycle

CD- Cycle Day

CD1- Cycle Day 1

CY#- Cycle Number

It’s all about cycles, right? These acronyms are super common, and you’ll have them learned by heart in no time.

O or Ov- Ovulation

DPO- Days Post Ovulation

It all revolves around ovulation. Contrary to common belief, the best chances of getting pregnant are actually 1-2 days before ovulation, so it is critical to be sure about your fertile window and ovulation date when you are trying to conceive. Also remember, that sperm can live around 5 days inside the female body. There are many different ways to help you figure out your ovulation date, but the most accurate are Ovulation Prediction Kits that measure the key fertility hormones that trigger ovulation.

LH- Luteinizing Hormone

FSH- Follicle Stimulating Hormone


These are key fertility hormones, which are responsible for triggering your ovulation or implantation. FSH typically decreases one or two weeks before ovulation and then, together with LH, rises and peaks around 12-24 hours before ovulation. Progesterone rises 3-7 days after ovulation and confirms there has been an ovulation.

FP- Follicular Phase

OPK- Ovulation Predictor Kit

OPT- Ovulation Predictor Test

Usually, Ovulation Predictor Tests measure LH in order to find out whether ovulation is close or not. When purchasing an OPK you should pay attention to the amount of hormones you can measure with it and how else it can help you on your journey to conceive- Pearl for example collects your hormonal data you measure each day and can therefore make accurate predictions about your ovulation and charts your hormones through your cycle. This way you don’t have to guess when the best time to take a hormonal measurement is, you know (find out more here).

EMU- Early Morning Urine

FMU- First morning urine

POAS- Pee On A Stick

Since your hormones accumulate in your urine overnight, it is advisable to take OPKs with first morning urine. This way, mistakes in measurements can be prevented. Most OPKs come with hormonal tests strips (or “sticks”), which you then expose to EMU.

BBT- Basal Body Temperature

BBTC- Basal Body Temperature Charting

CM- Cervical Mucus

These are other methods of determining your ovulation and fertile window. Most of the time, your body temperature rises slightly during or after ovulation. So, in order to find out your ovulation date while using the BBT method, you need to carefully chart your temperature over a few cycles in order to know when your next ovulation could happen.

Please note that this method can easily be influenced by different factors, and that your ovulation doesn’t necessarily has to be on the same day every cycle (that would even be an exception). You can find out more about this method here

Your Cervical Mucus usually thins down and gets clearer around ovulation, in order to make it easier for sperm to get through. Cervical Mucus monitoring can be a good, accompanying method to e.g. OPKs, because you learn a lot about your body. It’s not advisable to only use this method when TTC though, because like BBT, Cervical Mucus is also prone to be influenced by a lot of different factors.

TWW or 2WW- Two Week Wait

After Ovulation, you’re entering the Luteal Phase of your cycle or as many couples trying to conceive like to call it: The Two Week Wait. It has this name because about two weeks after ovulation you either get your period and a new cycle starts, or your period doesn’t occur which can often be a strong indicator of pregnancy.

SAAF- Stay Away Aunt Flo

AF- Aunt Flo (Period)

Also very common acronyms and while trying to get pregnant one of the most unwished-for body functions.

BFN- Big Fat Negative

BFP- Big Fat Positive

These acronyms refer to the results of pregnancy tests. There are different kinds of tests, and depending on the brand you either get two lines or “pregnant” as positive result. Don’t worry if you don’t get that “big fat positive” right away, as mentioned above, getting pregnant can be a challenge for many and is prone to many influencing factors. If you’re e.g. 35 or older, the time it takes to conceive is approximately 10 months on average.

If you have been trying to conceive for over a year without medical assistance, and no pregnancy has occurred, you might consider making an appointment with a fertility specialist in order to preclude health conditions that might interfere with conception such as blocked fallopian tubes or PCOS.

Below you can find some of the acronyms used for different fertility related diagnosis and treatment.


FS- Fertility Specialist

PCOS- Polycystic Ovary/Ovarian Syndrome

Polycystic ovarian syndrome (PCOS) is the most common hormone disorder in young women, about one in every ten is affected. People suffering from PCO syndrome have an elevated level of male sex hormones (androgens). Increased hair growth, cycle disorders, acne or obesity are some of the symptoms. About three out of four affected women have many small vesicles in the ovaries - the so-called polycystic ovaries - which give the disease its name.

The vesicles do not mature completely in many patients. As a result, ovulation does not occur and those affected cannot become pregnant. Women with PCO syndrome also have an increased risk of diabetes and cardiovascular disease. However, there is an ongoing debate on the degrees of PCOS, its classification and how it affects different women.

Endo- Endometriosis

Endometriosis is a widespread disease associated with severe pain. Severe menstrual pain is a very common symptom. In endometriosis, cysts and inflammation occur, which settle e.g. on the ovaries, intestines or peritoneum. Their tissue is similar to that of the lining of the uterus and can grow and bleed with the hormonal cycle. About 40 to 60% of women who involuntarily remain childless have endometriosis.

IF- Infertility

IW- Infertility Warrior

UI- Unexplained Infertility

Couples who don’t have chances to get pregnant without medical assistance classify as infertile. In the context of fertility awareness, it is important to differentiate between subfertility and infertility.

DI- Donor Insemination

AI- Artificial or Assisted Insemination

IUI- Intrauterine Insemination

ICI- Intracervical Insemination

Donor sperm treatment consists of inseminations that can be done by intrauterine insemination (IUI) or by intracervical insemination (ICI).

During semen transfer, the sperm cells are transferred directly into the uterus - usually when the partner has too few or insufficient mobile sperm. Sperm transfer is considered to be a less stressful method for the woman - despite previous hormone treatment.

IVF- In-Vitro Fertilisation

In vitro fertilisation (IVF) takes several weeks: After hormone treatment, oocytes are removed from the ovary and mixed with the partner's sperm in a test tube. If fertilisation takes place and the fertilised eggs continue to develop, an embryo is transferred back into the uterus. IVF is not a choice, it is a treatment for infertility.

Angel Baby- A baby who has been lost during a pregnancy, or a miscarriage

It’s sad as it is common: 60% of conceptions result in early pregnancy loss Rainbow baby- A baby born following a miscarriage

Snowbaby- Frozen Embryo

Baby Dust

This term is used to wish someone good luck with conceiving a baby. Sticky Dust on the other hand, is used when you wish someone good luck with a current pregnancy.

HAB- Having A Baby

HAH 9 months - Happy And Healthy 9 Months

These acronyms are probably the ones most wished for in the TTC community.
