You have supplied very little information - a more realistic question might be how long is a piece of string? I won't go re-writing all the factors that will influence what you should do - they have been written many times across the threads so you should settle down and get reading, and suffice to say there is no blanket answer for everyone anyway. If you don't have the time to do the reading then maybe a trial-and-error approach is what is required. Try waiting 60 days from the date of your last apps and see what happens? Needless to say, the longer, the safer.

Good luck.
