@Tasha_Baber the desogestrel mini pill completely stops your real natural periods. Any bleeding is a side effect of the pill. Irregular bleeding is a particularly common side effect of the mini pill, especially when you’re new to it, so unfortunately yes what you’re experiencing is common. Ideally you do not bleed on the mini pill.
There is no point tracking bleeding as it’s not actually a period, it’s an irregular and unpredictable side effect of the pill. You are no longer ‘due’ or ‘late’ or ‘on time’ for bleeds.
