Thanks for the query.
As you took the pill within recommended time possibly it can give protection.
Though you were around the ovulatory period, if you took the pill within 72 hours the protection can be expected.
The percentage of protection will decrease with increasing time gap between the act and intake of pill.
By considering all these points the possibility of pregnancy
is less in your case.
So you wait for your expected date of periods and if you miss the date go for pregnancy test once.
