No there is nothing to worry about. If she is she is.
It took my male till he was 10 1/2 months. I know my male was 7 months and he locked with both my Dams. (This was an accident.) None of them got pregnant.
Count the days since they mated. She should show between 5 1/2 - 7 weeks.
If that's the case she should be checked by your Vet. Also a high protein & calcium diet is recommended (Puppy Food) as soon as you think she is pregnant.
