What Does DPO Mean?

If you have spent any time on pregnancy messaging boards or forums, you have probably come across abbreviations like TTC, DPO or PG. Many women visit chat rooms and websites as they are trying to conceive. While getting the support of women in the same situation is a positive, it can be difficult to navigate through all of the slang that you will encounter on the messaging boards. To make things easier for you, we have compiled a list of some of the most common abbreviations like DPO.


One of the most common abbreviations that you will run across is DPO. DPO merely means “days past ovulation.” Women use this to talk about potential symptoms and decide if they are pregnant. It is also used to figure out at what point you can take a pregnancy test and have enough hCG in your body to actually get a positive result.

Ovulation occurs about two weeks before most women will have their period. Once the egg is released from the ovaries, it travels down the Fallopian tube where it will hopefully meet with sperm and implant on the uterus. Normally, you have up to 48 hours after ovulation to get pregnant. Afterward, there are another 8 to 10 days before the egg will implant itself on the uterine wall. Once this happens, your body will realize that its pregnant and begin to produce hormones like progesterone and hCG.


While abbreviations can be confusing, this one is fairly straightforward. TTC simply means trying to conceive. Since most people on fertility messaging boards are trying to conceive, you will see TTC a lot.


This acronym could leave you completely confused unless you already know what it means. BD technically stands for “baby dance.” It is a PG way of saying that the ladies on the forum are having sexual intercourse and trying to get pregnant.


On messaging boards, PG does not mean a kid-friendly movie. Instead, it stands for “pregnant.” If you see someone post PG in their comment, send them a round of congratulations!

SI or PI

These acronyms are used to mean primary infertility or secondary infertility. Primarily infertility means that someone is having difficulties getting pregnant for the first time. Meanwhile, a woman with secondary infertility is having problems getting pregnant after they have already had at least one child.


You will see this acronym a lot. While most people just call their husband their husband, messaging boards use the word “dear” beforehand. As a result, these acronyms mean “dear husband” (DH), “dear boyfriend” (DB) and “dear fiance” (DF). Sometimes, women will even use DD or DS for dear daughter or dear son.


This is another abbreviation on pregnancy forums that is incredibly common. LMP stands for last menstrual period. If you are trying to figure out your ovulation date, due date or if your period is late, someone will probably ask you for your LMP date.


With ovulation guides, predictor kits and pregnancy books easily available, many women track their cervical mucus (CM) to see how close to ovulation they are. EWCM means egg white cervical mucus. You might also see someone write HCM, which means hostile cervical mucus.


This is the least fun abbreviation of all. It means “two week wait.” After ovulation, ladies have two weeks to wait until they can (hopefully) miss their next menstrual cycle.


MC is the last thing you want to see on a fertility site because it means miscarriage. It is also sometimes written as m/c.


Another common abbreviation on fertility boards is OPK. These letters stand for ovulation predictor kit. Meanwhile, OPT means ovulation predictor test. Since both items are the same thing, these acronyms can basically be used interchangeable.

If you have spent any amount of time on fertility forums, websites or messaging boards, you have most likely run across these acronyms. Now, you are ready to take charge as you TTC. Good luck!
