2 periods only 1 week apart?

I’ve been having weird periods but they would always just come late. For ex: I’d have a normal 6 day period and then a little over a month later I’d have another normal 6 day period but this time it’s another period just 1 week since the last one. Idk what’s going on.

This months cycle.

The example of the month late period.

Had a period in August and then skipped September and then had a normal 6 day period in October and a normal 6 day one in November and then this new one.
