do I need to use another form of bc

kay • 20| UT
okay I've been on the pill since January and I was on Tri-sprintec and then I switched Pharmacys and they gave me Tri-linyah because they said it was the same power just different brand...so my question is since I'm starting a new brand will it take 7 days to be effective or will I be protected as usual? 
Sorry I posted this in the pill group and nobody would answer me. Thanks.
