As a breeder I would NEVER breed any dog under 5 pounds. so with that said, is very posible your girl IS pregnant, make sure she eats a GOOD quality puppy kibble and be ready for a posible C-Section. also NO calcium during pregnancy. wishing your girl the best, this is going to be a VERY stressfull time for her and YOU, because she is very small. also x rays at day 58 to see if her pelvic bone is big enogh, otherwise schedule a C-section.
hugs,
