Hi @O_DP_T1 ,
Have you checked your pen is working properly? You should be able to fire 20 units into a needle cover up to the red line on the picture illustrating below....
Try a new cartridge & needle too. The bung in the insulin cartridge could be jammed or dragging. It's also possible the needle maybe clogged?
If not? Discard the actual pen

What was your BG pre bolus.? (Before you ate?)
