Birth control help

So I started this new mini pill named slynd last month (June) and I got my period during this week week of active pills (I’ll include a picture) and then only spotted once on the placebo pills for the month.

Then fast forward to this month July. My period did not come around the same time in the pack. Now I’m about 4 days away from starting the placebo and still no sign of my period. Should I worry?
