What Causes Delay In Periods?

Hi Doctor....



I really nee your help.

I involved in a foreplay with my fiancee but never had intercouse with her. we just pulled down and try to feel each other and rubbed our private parts. We had this on 6th September. After that she got her period on 9th September. But that was not the full period but a smaall one only for two days. Last month she had continuously used "Regestrone" (around 10 days) tablet to delay her periods.



for this month her periods was due on 2nd of october but still she has not got her periods.



I am really getting very tensed whether its because of regetrone or beucasse of our foreplay.
