Hope springs eternal. Goats will have a VERY distinct sticking out on BOTH sides of the abdomen, where when they are NOT PREGANENT they have a skiiny indentation. Oh, and milk bags get BIG a few days before delivery. If she doesn't look like there is a basketball waiting to fall out the back, she's not delivery soon or at all maybe. They look skinny for the first two monthes, but the last one shows many physical changes.
Beides, goats usually only breed in months ending in R. (sept - dec) for late winter/ early spring babies.
