Can I be pregnant if I missed a pill in the 3rd week of taking Slinda?

Slinda tablets should be taken every 24 hours. If you delay taking any single tablet for up to 24 hours, the contraceptive effectiveness is not reduced. You should take your tablet as soon as you remember, and take your next tablets at the usual time. However, if the delay in taking the tablet was longer than 24 hours, there is a risk that the effectiveness will be reduced.
In this case, follow the following scheme: "If you miss taking the pill in the third week of taking the pills, the risk of reduced contraceptive effectiveness is significant, due to the upcoming 4-day break in taking the hormone. However, by adjusting the pill regimen accordingly, it is still possible to prevent a reduction in contraceptive effectiveness. You should take the last missed tablet as soon as you remember, even if it means taking two tablets at the same time. After that, you should continue to take your active tablets at the usual time. It is recommended that the patient does not take the placebo tablets immediately, i.e. without taking a break between packs – start taking the active tablets from the next blister."
