PBZ strange one

Early May I won 3 separate prizes in Premium Bonds draw.
I checked the numbers on my App
I checked when paid into my bank a few days later all was as it should be
Surprisingly today a 4th prize entered my bank account with a separate number not shown on the App
Given that June's Draw is 2nd of June then am I early or was the 4th one late?
If I am early then June has already been drawn..............
For clarity each prize was £25 so no MC20 thingy for me
