Credit card companies report you as being delinquent to the three major bureaus after you have been late on your payment for 30 days or more.  In your case, you have been late for 67 days, so your credit score will already have been affected.  Your credit card issuer reports to the three major credit bureaus every 30 days, so it is very important that you make a payment immediately to avoid being reported as 90 days delinquent, at which point your credit score will take another hit.  The effect that your late status will have on your credit score will be marginal and can be repaired if you practice responsible behavior for the next 12 months.
However, you should check your next credit card statement carefully or call your credit card company now, because your interest rate may have very well gone up (perhaps considerably) due to your late status.  Being this late on your credit card payment could have a costly effect on your wallet, depending on if or how much your interest rate has increased.  If it has skyrocketed, you should try to pay your balance off in full.  If you can’t do that, you may want to consider a balance transfer.
