Confused about Clear Blue easy digital opks...

A • TTC double Rainbow baby. Miscarriage in February and Ectopic in May. 💕 it will happen- I just know it 🙏
How curious if anyone else find that that clear blue easy digitals become positive (smiley) way before other brands? I also don't really understand why they say to use your first morning urine when every other opk has you use mid to late afternoon urine. These two photos are tested with the same urine... Any one have any insight? Has this happened to you? I'm only cycle day 9 and I usually ovulate around cycle day 17 but I'm testing way early this month because this is our first month ttc after an ectopic. Thanks in advance!
