I've learned quite a bit over the years, but I still don't understand how your score can drop (only by a point or two, but still...), if only slight positives occurred and nothing negative. I logged on to my Chase app, and checked my Credit Journey, and it stated my point went down. When I clicked on "what's changed".....this is what it gave me:
What's changed since Feb 20, 2022?
-1 pt
Your credit score went down to 739.
^ 1,209 Your available credit went up.
-1%
Your credit usage went down.
-$609
Your total balances went down.
Again, it's only one point, but all those things were a positive....so why did it drop?
You've already gotten really good information, so I'll just add a couple of things: first, good job on getting your scores up! That's an awesome improvement. 
Keep up the good work and you're going to be looking at 800s one day soon. As for scores fluctuating, if you're interested I'll post screenshots of my WILDLY varying scores! I mean 50, 60, 80 points OR MORE from one month to the next!! And I don't sweat it.
Do understand, though, that there's a reason I don't sweat it: I expected it. Right now, while spending a lot of money on credit cards renovating my house, my utilization rates (both per card and overall) have gone up, hence my scores have gone down, but no worries. I'm not seeking any credit, nor will I be any time soon, so lower scores really have no effect on me. At this moment, because some big charges haven't hit my reports yet, my scores are still in the 800s, albeit lower than usual, but once everything has posted they'll go down at least 50-60 points. The screenshots I'm offering to post are from previous times my scores fluctuated.
The bottom line is that scores do fluctuate, and unless there's something unusual causing it--like charges you didn't make--they're generally not anything to worry about. Minor dips usually correct themselves quickly, so if you spend more than usual one month and then see your score drop, don't worry, just pay your bill and you'll see your score go back up.

I know they can fluctuate, but I am just curious why mine dropped when the only changes it gave me were positive. I plan on trying to buy a house next year, so I'm paying a little more attention to my score.
Oh, you're welcome!
As for the minor drop, as @Remedios said, the answer is.... who knows?! 
No, seriously, it seems like scores can move up or down in the blink of an eye. If you hang around here for a while, you're going to see that us old-timers (credit-wise...well, in my case, age-wise as well) just don't worry about small fluctuations. The only time I would be concerned is if there's a truly unexplained change of significant points. One or two points? Not significant!
It's good to watch your scores like a hawk; I do, and I think it's a great habit to get into. But going in you need to realize that your scores will change, for any or no apparent reason--and even when a reason is provided, it may not make ANY SENSE at all! I have a thread about Equifax right now, how its 'reasons' make no sense whatsoever, like the one that says the highest credit limit on my cards is too low. Um....my highest CL is $15,500! THAT'S too low?! Ridiculous. Learn early to take alll this with a grain of salt!
