normally you would breed on 9th and 11th or 10th and 12th day of heat. some girls will accept the male at any time during the heat.
morning sickness usually occurs during the third week of pregnancy (of course that is the norm and could be different amoung different girls).
most of the time you will not see a physical change until the 45-55 day of pregnancy. if you need to know, you can take her to your vet at about the 30 day and they can examine her.
good luck to you.
