If I take Slinda again after a few days break, am I immediately protected?

The blister ended a few days break and from the new blister I started taking the medicine

I finished the package a few days break and started taking it again

No, if you have stopped taking the pills and returned to them on any day of the cycle, protection may be reduced. You will be fully protected only when using Slinda tablets from the next blister. When taking tablets from the current blister, an additional form of contraception in the form of a condom should be used.
