preg or not?

Question
Out chihuahua was breed and today is her 60th day.  Her nipples have liquid when you pinch them, and she has been nesting, her temp has been going from 101 down to 98.2.
Her stomach isn't that much larger and I can't feel any puppies. She "hooked" up at least 4 times. Is she preg or is this false preg. Or is it a few days to go? Any help will be greatly appreciated.  

Answer
Hi Sherry,  The gestation period is 63 days, and can be from any of the days she tied with the male, so you count from the first day & the last day.  That is the time period she is due.  Odds are that she is pregnant, but just to be sure you can get x-rays.  If this is her first litter, she will hold them up under her ribs more, so a lot of times you won't see the stomach get as large.  Hope this helps,

Dawn
