hello, welcome to HCM, I am Dr. Das
look, you have taken too much pills in a monthly cycle. for your information, in a menstrual cycle, if you are able to take all the drugs, then you do not need anything extra for protection against unwanted pregnancy
SO, as a side effect of these drugs, you may experience this type of delay in period and also some irregular bleeding.
For a period, you have to wait for 7 more days. But before that do a home pregnancy test just for confirmation.
After that if she does not have her period, you have to consult with her gynecologist for further management.
