Thanks for the query.
If you continued the new pill after stopping the old pill as per schedule, you can expect full protection.
If you have taken gap more than recommended, you have to use some additional method of contraception
like barrier method for at-least one week after starting the new pill.
As you know this new pill also you have to take at same time of the day for better results.
