How many gifts is "too much"?

Hello! I'm facing a bit of a dilemma of some sorts.

​Basically, in a few months I'll be meeting up with a friend of mine that I met around 2y ago on a school trip. We're both the same age, we clicked and then just kept touch online. The plan is that I'll be staying with her and her family for 3 days and we'll just hang out and stuff.

​We planned the trip over half a year ago, and during that time I've been slowly accumulating gifts for her. Nothing big, for example I could be walking through the mall or scrolling through some online shops from boredom, see something that catches my eye and think "Oh, she'd like that" and buy it.

I​t's never anything expensive, I'm not rich unfortunately, but I always try to make sure it's something that she mentioned to me at least once. Sometimes when I'm not sure, ​I even outright text her if she'd like this specific thing, just to make sure.

I mentioned this to one of my friends, so she got curious and asked me what did I get her so far? So I listed off what I could remember, and according to my friend I'm "going to far".

N​ow just to make sure, I'm not expecting anything in return. I always buy/make handmade gifts for people that I love, whether it's a special occasion or not.​ I suppose gift giving would be sort of my love language?

So I just wanna know, should I like, spread the gifts and not give my friend everything all at once? Although to be fair, her birthday is gonna be a month after my visit, so I also have stuff prepared for then, if that makes sense.

I can add the gift list in the comments if that'd help anyone​
