well..it has side effects.
firstly,belated congrats on wedding.
2ndly,its a bad idea to be put on OCP's(oral contraceptive pills)even before and then immediate after marriage.
i didnt understand at all the reason for the doc to tell her to continue medicine even when you are abroad.
she can consider taking the OCP's before your arrival that matches with her periods date.although they take time to act on body so this might not be succeful.
since your stay duration is so less,why dont you practice the barrier method like condoms,or withdrawal method which seems more healthy.
bcz long term side effects are that pts are going to have tough time conceving once they get off the OCP's.
then you will be coming her to ask for tips and reasons of delays in pregnancy.
