First of all, it's almost impossible to determine when you'll have you next lucid dream unless you WILD. Most DILDs relate to specific causes that are verified and up triggering a lucid dream. Some reasons people have a DILD:

- Dream incubation (intentional or not intentional);
- Prospective memory;
- Residual memory;
- Pattern recognition;
- Brain chemistry;

Second of all, having great dream recall don't mean that you are automatically set for having lucid dreams. Many people forget that in order to strengthen the connection between dream recall and lucid dream you need to work with your dreams. This can mean actively looking for dream signs, finding patters in them, identifying the possible reasons why you didn't become lucid, among others.
On another note, just because your dream recall isn't great it doesn't mean that you're far from lucid dreams. Even many of expert lucid dreamers have loads of dreams in which they don't achieve lucidity, and you're just starting!

Try to focus on dream journalling and some technique and don't worry when the lucid dream is about to come, it will come eventually, but there's no way to predict when.
