So I’m assuming that yellow pills are the active ones on your brand? First of all, you can skip your break as many times in a row as you’d like to. However, skipping your breaks causes some people breakthrough bleeding which seems to be the case with you (since you don’t get a ”period” at all on the pill, so any bleeding during your active pills is just breakthrough bleeding). So no it’s not starting to stop working or anything, all you’re experiencing is a normal side effect of the pill, even if you’ve been on the pill for a long time it’s still normal to experience new side effects x
