Birth control and unexpected spotting

So I’ve been on the pill since January, and I took it regularly up until June because I was moving and my didn’t have pharmacy didn’t have it

I started it again around late July/early August, and I’ve had brown discharge (what looks like old period or spotting)

It’s the same pill, brand, dose, etc. is this normal for me to be spotting like this, especially when i didn’t at all when I started the pill?
