Too many abbreviations.

So I see a lot of people asking what things are because there's a lot of abbreviations on this app instead of just saying it but anyways the few I have now figured out are listed below for those who do not know them.
BFN - Big Fat Negative 
BFP - Big Fat Positive 
BD - Baby dancing 
DPO - Days past ovulation 
OPK - Ovulation Predicter Kit 
AF - Aunt Flow (Period) 
BBT - Basal Body Tempeture 
CM - Cervical Mucus 
TWW - Two Week Wait. 
If you know anymore, comment thanks!!👇🏼
