If I have forgotten the tablet (Vibin) several times within a month, and I use the new packaging regularly, will the effectiveness be maintained or reduced?

If you missed a pill in week 3 of contraception, follow the manufacturer's recommendation: "Take the missed pill as soon as possible, even if it means you have to take two tablets at once. The next tablets should be taken again at the usual time. Instead of using white placebo tablets from this blister, they should be discarded and start taking the tablets from the next blister. Bleeding is likely to occur at the end of the second blister tablets, while taking the white placebo tablets, but spotting or midcyclic bleeding may also occur when taking the tablets from the second blister." Taking into account the description of the situation, it should be assumed that contraceptive effectiveness may not be maintained when several pills have been missed during one cycle (if you were sexually active at that time, this is an indication for consulting a doctor). From the moment of the last skip, I suggest using additional methods of protection (condom) for 7 days, and take the next tablets punctually.
