Should I continue taking Zoely tablets if I am already using the second pack and still do not have withdrawal bleeding?

Hello, I finish the second pack of Zoely tablets. I am currently on a second placebo tablet and it is not expected that withdrawal bleeding will occur. The first time he was gone, too. I would add that I take them very systematically, I have never missed a tablet more than 10 minutes. Two weeks ago, for the first time, I loved my boyfriend - we also secured ourselves with a condom, and also did not end up inside. My guess is that the chances of pregnancy are close to zero, so if for the second time withdrawal bleeding does not occur then should I continue taking the tablets? I used Belara before and there was no problem with bleeding, so the lack of it with Zoely makes me very stressed.
