pretty normal, honey -- we waited to tell MIL until 12wks with a scan becasue I didn't want to upset her if something went wrong again (1 mc and two possible chemicals); I did tell my own parents at 10wk but said it was unofficial until we were a bit further along, but I wanted my mom to know in case.....I told my overall boss as soon as I found out as was again scared of mc and didn't want to have to explain if I needed time off (again....)
how far along are you? (and how many losses?)
However, your mother at least might be very upset if you don't tell her as mc is very, very hard to deal with all on your own -- what about FOB/OH? How do they feel?
try and take care of yourself.....
best wishes
