The best way to tell how far along she is in her pregnancy is to take her into your vet for an exam. The vet can do a blood test looking for the hormone relaxin that is produced at 22 days gestation or later. Further along in her pregnancy, x-rays and an ultrasound can be done to better pinpoint at which point she is at in her gestation. Regular vet care is very important for a pregnant dog, so I would take her into the vet sometime this week for an exam.
