if you google fertility abbreviations you should find a list somewhere .. there is one on here I think .. but a few are: af = aunt flo or your period .. what we don't want! BFP is big fat positive meaning a positive pregnancy test and BFN is big fat negative - not this time
pg = pregnant, DH = darling husband .. same goes for DD (daughter) DS (son)
I'm sure there are lots more but I can't think of them right now .. if you list some I will try to answer for you .. it is tricky at first but they will soon become a 2nd language!
