TTC Acronym Meanings: Meaning of AF, BFP, BFN & More

When it comes to the experience of pregnancy, understanding the language used to discuss a pregnancy is essential.

In this blog post, we’ll discuss what “BFN” stands for in the context of pregnancy and how it might affect your decisions. We’ll also discuss what other terms are used to discuss pregnancy health, so that you can be informed and empowered throughout your pregnancy journey.

With all the acronyms on TTC (trying to conceive) message boards, it can seem like a whole new world for those hoping to avoid AF and see a BFP. Here is a primer on some of the most popular ones.

Online message boards are an excellent source of information when you’re trying to conceive and looking for solutions. In a supportive environment, expecting parents can find encouragement, inspiration, commiseration, and knowledge from others who are either on the same path as them or who have “been there, done that” and have children to show for it.

However, the confusing array of acronyms used in the TTC (trying to conceive) community can seem like a completely different language on your first visit to a message board, which can be frustrating when you’re looking for a quick answer to a question.

It’s easy to feel confused even if you’ve been active on other message boards for years and are familiar with some of the common acronyms, such as SO (significant other), DH (dear husband), OP (original poster), SAHM (stay-at-home mom), and so on. What does that member mean when she claims that her RE recommended an OPK, why is everyone so worried about the TWW, and what do women mean when they claim to have received a BFN following a POAS mean?

Fortunately, learning the language is quick and well worth the effort. Here is what you need to know to make the most of the online TTC community, from finding a board advice to understanding the lingo.

Finding a TTC board is quite easy. Along with the main board, the What to Expect TTC board also features a number of groups created by members, or you can create your own group. Less people participate in member-created groups, but they provide a more private experience.

A web search for “trying to conceive,” “TTC,” and terms like “discussion board,” “forum,” or “community” will return pages of results in addition to the WTE TTC boards.

Make sure you are a good fit for a community before you decide to join it. Check out a few of the conversations to get a feel for the atmosphere. Look for a lot of interaction—joining a board where nobody ever posts is pointless. Additionally, ensure that the forum is simple to navigate and well-moderated (to prevent internet trolls and unnecessary drama).

Simply put, they make things a whole lot easier (once you know some of the most common ones), so what’s the deal with all the weird acronyms?

It can get tedious to type out the entire phrase every time you post in TTC talk because some terms, like “micro injection fallopian transfer” and “artificial insemination from husband,” are quite lengthy. The use of acronyms by TTC forum users is the reason why “micro injection fallopian transfer” (MIFT) and “artificial injection fallopian transfer” (AIH) are both used. Much simpler, right?.

Here is a list of some of the most typical acronyms you’ll see to make things even simpler:

  • AF: Aunt Flow (aka your period)
  • BC: birth control
  • IF: infertility
  • PCOS: polycystic ovary syndrome (a condition in which the female sex hormones are out of balance, which can prevent ovulation from occurring regularly and make it more difficult for a woman to get pregnant) Trusted SourceAmerican College of Obstetricians and GynecologistsPolycystic Ovary Syndrome (PCOS)See All Sources [1]
  • BFN: big fat negative (a negative pregnancy test)
  • BFP: big fat positive (babys on board!)
  • EPT: early pregnancy test
  • hCG: human chorionic gonadotropin (a hormone produced during pregnancy; elevated levels result in a positive pregnancy test) Trusted SourceCleveland ClinicHuman Chorionic GonadotropinSee All Sources [2]
  • HPT: home pregnancy test
  • PG: pregnant
  • POAS: pee on a stick (take a home pregnancy test)
  • TWW: two-week wait (the two-week period between ovulation and when you can test for pregnancy)
  • CNM: certified nurse midwife (a nurse — usually an R.N. — who has completed graduate-level programs in midwifery and is licensed by the state and usually has a collaborative relationship with a physician)
  • OB or OB/GYN: obstetrician or obstetrician/gynecologist
  • PCP: primary care physician
  • RE: reproductive endocrinologist (a doctor who specializes in treating reproductive disorders and infertility in women and men)
  • BBT: basal body temperature (the bodys temperature upon first waking up in the morning; its tracked using a special thermometer and rises sharply around the time of ovulation, helping a woman to determine when shes fertile)
  • CD: cycle day (usually followed by a number, the cycle day is when a woman is at in her menstrual cycle; if the average cycle is 28 days, CD1 is the first day of your period, and ovulation usually occurs at the midpoint of the cycle, though timing varies)
  • DPO: days post-ovulation (the number of days since ovulation — e.g., 4 DPO; the term is usually used when someone is waiting to take a pregnancy test)
  • EWCM: egg white cervical mucus (the clear, slippery egg white-like discharge that occurs near ovulation)
  • O: ovulation (or ovulated)
  • OPK or OPT: ovulation predictor kit or ovulation predictor test (urine or saliva tests that can detect an upcoming ovulation 12 to 24 hours before it happens)
  • AI: artificial insemination (sperm is inserted into the womans uterus using a catheter)
  • IVF: in vitro fertilization (a procedure used to treat infertility where an egg is fertilized with a sperm outside the womb and then implanted in a womans uterus) Trusted SourceAmerican College of Obstetricians and GynecologistsTreating InfertilitySee All Sources [3]
  • EDD: estimated due date (the estimated date a baby might be born, determined based on the first day of a womans last menstruation or estimated date of conception)
  • LMP: last menstrual period (the first day of your last period)
  • MC or M/C: miscarriage
  • US: ultrasound
  • Aside from the acronyms, some terms can be confusing. One who has been a part of the group for a while (often years) and volunteers to welcome new visitors to the board, introduce them to other members, encourage participation in conversations, and help ensure the board runs smoothly by reporting violations to the moderators is known as a “den mother,” who may appear on some message boards but not others.

    You’ll also come across the phrase “baby dust” on many TTC forums. “People wish for others to have a lot of sticky baby dust, throw it at them, and sprinkle it on them.” Baby dust is just a super-cute way to wish someone who is trying to conceive luck on their conception journey, so what’s all the fuss about?

    What does BFN stand for in pregnancy?

    A BFN, or big fat negative, is paired with a BFP, or big fat positive, which is obviously not what you want to hear if you’re trying for a baby.

    You may have also heard of the BFP pregnancy test. This works by dipping a strip of litmus paper into a container of your urine. It%E2%80%99s arguably easier than peeing on a stick, and up to 99% effective! Of course, while a BFP is likely to be a true representation (false positives are extremely rare), it%E2%80%99s not always the case with BFNs

    One reason for this is timing your pregnancy test. It can be simple to become discouraged and inform everyone that you have experienced a BFN, but it may only be a matter of timing.

    It’s likely that you’re dealing with a lot of new medical terms and acronyms if you’ve recently been thrust into the world of infertility. For those who are TTC (trying to conceive), here is a helpful list of the acronyms that are most frequently used on message boards and in articles.

    IUIIntrauterine insemination (the process of inserting sperm through a catheter into a woman’s uterus)

    Pregnancy tests use human chorionic gonadotropin (HCG), a hormone produced by the placenta after implantation, to determine whether a woman is pregnant.

    TWWThe period of time between ovulation and the start of a pregnancy test is two weeks.

    IVFIn vitro fertilization (IVF) is the process by which a woman’s eggs are removed from her body and fertilized externally to create an embryo, which is then placed inside her uterus or that of another woman.

    BFP = big fat positive (as in pregnancy test) BFN = big fat negative. AF = aunty flo as in your period. Good luck TTC (trying to conceive) if that’s what you’re up to, OP! (Original Poster).
