Clearblue digital OPK

So yesterday was my first day using the clearblue advanced digital opk, according to Glow I wasn’t set to ovulate until 3/3. I was using Equate opk and they were awful, so I went for it and got the pricey no confusion opk kit...so yesterday I got a low reading and this morning I got the solid smiley face! No flashing smiley for “high” just straight to peak...has this happened to anyone else? Should I trust it’s correct? This is my first cycle using opk so I’m really new to it and want to ensure I didn’t mess something up starting to test too late or something. Thank you in advance and baby dust to all!
