Clearblue advanced confusion

This is my first time ever using ovulation tests, so I’m picked up what was available at the store, which was Clearblue advanced. We started trying a little later in the month so I started testing on CD 14(5/23) and it read low, which was expected because these ones always give a low result on the first test unless you’re peaking. I tested the next day(5/24) and it gave me a peak reading, so Glow said ovulation was expected 5/25. With this brand once you get a peak you can’t test again for 48 hrs. So I tested again 5/26 the result was another peak reading, so once I inputted that into Glow it changed the expected ovulation to 5/27.

So my question is, should I be estimating that ovulation happened on 5/25 or 5/27? Thank you in advance :)
