I try to explain the specialized TTC and IF abbreviations as I use them, but in case you’re ever confused, here’s a list of the most commonly used abbreviations and what they mean.
2ww | Two Week Wait Waiting to take a pregnancy test; the average length of the Luteal Phase [from ovulation to menstruation] is 14 days
AF | Aunt Flo Menstruation, period
BBT | Basal Body Temperature Temperature upon waking (before getting out of bed); useful for determining when ovulation has occurred
BD | Baby Dance Sex
BFN or BFP | Big Fat Negative or Positive Pregnancy test result
CD | Cycle Day Cycle days are numbered starting on the first day of your period
CM | Cervical Mucus Fluid excreted by the cervix, stimulated by estrogen. Becomes more fertile and receptive to sperm just before ovulation.
CP | Cervical Position Changes throughout the cycle, in a predictable pattern
DH | Dear/Darling Husband Sometimes used sarcastically
DPO | Days Past Ovulation Days are numbered starting with the day after ovulation (1 DPO).
EDD | Estimated Due Date When a baby is expected to be born; based on last menstrual period (LMP) or date of ovulation
ENDO | Endometriosis Health condition in which tissue that’s normally inside the uterus grows in other places, such as on the fallopian tubes and ovaries. This can cause bleeding, scarring, pelvic pain and infertility.
EWCM | Egg-White Cervical Mucus The most fertile type of CM
hCG | Human Chorionic Gonadotropin Pregnancy hormone detected by at-home pregnancy tests; also used to trigger ovulation
HPT | Home Pregnancy Test The stick you pee on
HSC| Hysteroscopy Procedure in which the doctor visually inspects the inside of the uterus via a tiny light and camera.
HSG | Hysterosalpingogram Totally fun diagnostic procedure in which a catheter is inserted through the cervix and into the uterus, and dye is injected into the fallopian tubes. All the while, your pelvis is under an x-ray machine, in order to see whether or not the dye goes where it’s supposed to go. Used to determine whether or not the fallopian tubes are blocked.
IF| Infertility The inability to conceive after having sex for 12 months (for women under the age of 30) or 6 months (for women over 30) with no contraception.
IUI | Intrauterine Insemination Procedure whereby semen is placed directly into the uterus via a catheter
IVF | In Vitro Fertilization Complicated process whereby an egg is fertilized outside of the womb, then transferred directly into the uterus.
LAP | Laparascopy Surgery that uses a thin, lighted tube put through an incision in the belly to look at the abdominal organs or the female pelvic organs. Laparascopy is used to find problems such as cysts, adhesions, and fibroids. Tissue samples can be taken for biopsy through the tube (laparoscope).
LH | Luteinizing Hormone When this hormone surges, it triggers ovulation (under normal circumstances). The surge is detected by ovulation prediction kits (OPKs) to determine if ovulation is imminent.
LP | Luteal Phase The time between ovulation and menstruation (on average, 14 days, but varies from woman to woman)
O or OV | Ovulation Release of a mature follicle by the ovary(ies)
OB or OB-GYN | Obstetrician-Gynecologist Trained physicians who diagnose and treat female reproductive health issues, and care for women during pregnancy, childbirth and during post-birth recovery.
OPK | Ovulation Predictor Kit Detects LH surge, which typically means ovulation will occur in 12-36 hours.
PG | Pregnancy, Pregnant Does this one really need further explanation?
PNV | Prenatal Vitamin A necessity for all women of childbearing years, whether planning a pregnancy or not.
RE | Reproductive Endocronolgist Doctor who specializes in fertility issues
SA | Semen Analysis Measurement of the amount of semen a man produces and the number and quality of sperm in the semen sample
TTC | Trying To Conceive Typically refers to those actively trying to get pregnant; also applies to anyone who has sex without using contraception
u/s | ultrasound Use of high-frequency soundwaves to look at the internal organs. In the TTC universe, the most common type is the transvaginal or t/v ultrasound, whereby a probe is inserted into the vagina in order to get a better look at the uterus and ovaries.
