Hullo Friends

MY MIA IS 22 MONTHS OLD. STRAY WHEN WE ADOPTED HER WITH HER BROTHER. they have mated for the first time on 9th feb 2015 at around 11pm ist. and if i calculate 63 days, it would be around 12th april, that she will give birth to her first litter.
we are excited also apprehensive about the whole thing as we are not financially independent lot.
the thing that worries me a lot, today, is that there was an opaque discharge like a thread after she pee'd that dropped down and she happened to see it and licked it. she came to know that it was her's so she started cleaning herself
the first thing that came to my mind is that is she about to deliver?
she is doing great. always hungry, for early dawn hunger binges, her bro max, is getting the rewards though alongwith her.
is she safe, folks with the opaque discharge?
