If I don't get a period after the first pack of Pinda, should I keep taking the new packaging or taking a break and waiting for the period?

If you take a break between blister, the drug will not protect against pregnancy. Bleeding may or may not occur while taking Slinda, but you should continue to take the tablets as before, without interruption in taking the tablets. An inconvenience that may occur while taking Slinda is the occurrence of irregular bleeding from the genital tract while taking it. Bleeding may also not occur at all. However, this is not an indication to take breaks to induce bleeding. As I have already written - doing so would be a mistake and could cause you to get pregnant unplanned: "you should take one white, active tablet for the first 24 days, and then one green tablet for the last 4 days. Then, you should start the next pack immediately, without interruption in the daily intake of tablets. So there is no break in taking the tablets between the two packs."
