So you鈥檙e TTC. But then you got a BFN and were so, so sad. That鈥檚 totally okay. Your OB said that even though AF made an unexpected appearance, you can start taking your BBT, do the BD, and get ready for a BFP. Whew! With all of these acronyms, it鈥檚 kind of exhausting keeping up with the latest pregnancy lingo. Don鈥檛 stress: We鈥檝e got you covered. Check out the pregnancy-related abbreviations you need to know RN! (Uh, that one would be 鈥渞ight now,鈥 and not 鈥渞egistered nurse.鈥)

1. AF = Aunt Flo: When she鈥檚 in town, the baby-making is on hold. When you鈥檙e trying to get preggo, this is one 鈥渞elative鈥 you don鈥檛 want to see. Aside from her visits ushering in a BFN (we鈥檒l get to that one later), this acronym is also used during pregnancy planning. After all, if you don鈥檛 know when AF is coming, you can鈥檛 calculate your ovulation days.

2. BBT = Basal Body Temperature: This one鈥檚 another part of the planning process. Your BBT is the lowest body temp that you have in a 24-hour period. Immediately after your ovulation day, your BBT goes up. It鈥檚 not a dramatic rise, but you鈥檒l typically notice a change in the 0.4 to 1.0 degree range. Charting your BBT helps you to better predict when you鈥檒l ovulate 鈥 and that can lead to a BFP (we鈥檒l get to that one too).

3. BD = Baby Dance: This isn鈥檛 the goofy happy dance that you do when you find out that you鈥檙e expecting. It鈥檚 the old-fashioned way of getting preggo 鈥 a horizontal mambo, if you will. That鈥檚 right: A BD equals the kind of sex that can get you pregnant.

4. BFN = Big Fat Negative: No hopeful mama-to-be wants to get a BFN. It鈥檚 shorthand for a minus sign, the lack of a second line, or a 鈥渘ot pregnant鈥 on the little stick test.

5. BFP = Big Fat Positive: Yay! A BFP means it鈥檚 time to celebrate. It鈥檚 the opposite of a BFN, meaning the teeny-tiny pink plus sign just popped up on the test. When you finally get that BFP, it means your body has started its way down the nine-month road to bringing you a kiddo of your very own.

6. CM = Cervical Mucus: If you鈥檙e charting ovulation symptoms, your CM is majorly important, but since few people want to talk about 鈥渕ucus鈥 in any context, the CM acronym is kind of necessary. Your CM will seem slippery and get an egg-white consistency right before ovulation. And yes, you need to feel it to tell if your body is ready for some serious baby-making.

7. FTM = First-Time Mom: This is you! In the maternity world, a FTM is exactly what she sounds like 鈥 someone who is going to be (or already is) a mama for the very first time. Way easier to say than the super-technical 鈥減rimigravida,鈥 if you ask us.

8. HPT = Home Pregnancy Test: It鈥檚 that thing that actually gives you the BFN or BFP: You know, those pencil-like pee sticks that tell you if you are or aren鈥檛. While HPTs used to be super-simple, technology has upped the ante and given mamas-to-be options that even include Bluetooth-enabled devices.

9. LP = Luteal Phase: The time between when you ovulate and when AF comes to visit is your LP. If you鈥檝e gotten a fertilized egg during your LP, the lining of your uterus thickens and preps for pregnancy, and you鈥檙e on your way to a BFP!

10. PG = Pregnant/Pregnancy: Simple but essential, this may be the most important acronym of pregnancy.

11. TTC = Trying to Conceive: You鈥檒l see this lingo pop up when anyone talks (or writes) about getting pregnant. It鈥檚 a handy way for folks to indicate that they鈥檙e actively trying for that BFP.
