Here's the patient information from the manufacturer for your brand of pill:

When the pill becomes fully effective when you first start has a lot to do with when you started it, though, information that isn't included there.
Did you start wither on the first day of your menstrual period, or on or before the first Sunday after it started? If so, given you have been taking your pills very well, then it was probably fully effective (that's 99% protection in one year of perfect use, 91% in one year of typical -- no one can give rates for less than one year, because that data isn't a thing anyone can have given how the pill works and is studied) within one week.
If you did NOT start at either of those times, though, it may not be fully effective until you are into your second pack of p[ills, so in that case, you'll want to use a backup method until next month.
Do know the BEST protection from pregnancy is always two methods, though, so if you want to be the most protected, you'll want to ALWAYS use a backup method with your pill, like condoms, for example.
