Yo.
Took me roughly a week to get my first one intentionally(And it was a WILD, out of everything), though i had one lucid dream before that it happened before i knew about lucid dreaming. But as JoannaB said, everyone is different on that. Congrats on being really close though, if you have realized that you were dreaming instead of asking and then woke up, it would have counted as lucid dream, nightmares are actually a good lucid inducers due to how extraordinary they are, so next time you might succeed.

Your recall and amount of sleep hours are also fine, as well as how you do reality checks, do you have a dream journal though? If not, get one or use one on DV, and start writing/typing dreams, not only it will help increase recall even further, but also will increase chance to get lucid.

Dream recall is pretty important, because even though lucid dreams are much easier to remember than non-lucid dreams, it's still possible to forget them without some practice, especially in the case if you were lucid not in the last dream, in which you can become lucid too, you can become lucid in any dream. That's how many people who are unaware of lucid dreaming become lucid in some dreams, but since they have no recall at all they just don't remember it.

Also there are no levels of lucidity i believe, either you are lucid, or not, but there are levels of awareness. As for the length, due to time dilation in dream, i think it is actually unlimited, since everything is possible in dreams, someone had dream that lasted a few years, my max was a couple of weeks, though i was only lucid near the end of it.

If you want, you can also visit dreamviews academy and it's intro class: , which is a good place for people who are new to lucid dreaming to start out.

Good luck!
