Switching birth control

JC

I recently switched to a new birth control pill and I know the doctors say to use extra protection for the first week or so. But i also read somewhere that you just have to use it for the first 2 days. My husband and I had sex after being on the new pill for 6 days and I totally forgot about the extra protection. I started the new pack right after i finished the other one. We should be okay right?
