Retake Policy
You can sit for (ISC)² exams up to three times within a 12-month period.
For the CISSP-CAT, CISSP, SSCP, CAP, CSSLP, ISSAP, ISSEP and ISSMP:
If you don’t pass the exam the first time, you can retest after 30 days.
If you don’t pass a second time, you can retest after an additional 90 days.
If you don’t pass a third time, you can retest after 180 days from your most recent exam attempt.
For the CCSP and HCISPP:
If you don’t pass the exam the first time, you can retest after 90 days.
If you don’t pass a second time, you can retest after an additional 90 days.
If you don’t pass a third time, you can retest after 180 days from your most recent exam attempt.

As this would be your 2nd attempt, if you fail you would need to wait 90 days before being able to attempt it again.
It's also worth noting, if you took the English language version before and would be looking to do so again you will be taking the CAT version so it's worth reading up on how the exam has changed:
