@oxfordinwinter85 Haha, oh GOD I have been sucked into the madness truly and now speak fluent TTC (trying to conceive).
AF you obviously know
POAS = pee on a stick i.e. take a pregnancy test, though I don’t know anyone who wees on them vs dips them in a cup
OPK = can’t remember what this stands for but it’s the stick you wee on before ovulation to test for LH (another abbreviation, a hormone), the surge you get before ovulation
EWCM = egg white cervical mucous, the vaginal goop you’re looking out for just before ovulation. Though whenever I read CM, which means cervical mucous, I just read “cunt mole” after a friend who has some spectacularly inventive swears. Also egg whites just makes me thinking of conception sex as “making meringues”
I refuse and will never use BD = baby dance, aka sex
But basically to chart your cycle, you don’t just look for temperatures, you also keep an eye on cervical mucus (you don’t have to go rummaging, just check your knickers to see if they look like someone sneezed) and you pee on OPKs, and those three things combined give you the full picture.
