Wait n watch. That is the only thing you can do. Are her periods very regular. 3-4 days here n there is not a big thing. It can be delayed because of stress. Pregnancy test can be done 10 days after missing your period. For example if your date was 10th, then do the test on 20th. Before that it can give false negative or false positive test.
