Missed Slynd pill and now keep spotting, when does it stop?

So I started taking Slynd last month (for PCOS rather than contraception, my period had gone AWOL), I’m on the second pack now. Had no spotting in the first month and a regular length, light “period” at the end of the first pack. I thought yay, I’ve escaped the spotting everyone complains about on this.

However, on this second pack, I forgot my pill last Tuesday, a week ago today (I take it before bed). Doubled up on Wednesday as the instructions said. Now since Thursday I’ve been spotting, which I know is expected for having missed a pill, but why is it still going now that I’ve taken them regularly for a few days :( It’s light, pretty much just noticeable on the toilet paper when I wipe, but I’m confused why it’s still happening 5 days later and now worried I will be one of the many who it continues for months.

Anyone experience similar?
