Today I did a delt injection, 1.5" 25G but only inserted an inch. When I pulled out some blood spurted out which I know is normal. My question is, did I lose any oil?

I know you are supposed to pull back on the plunger to see if blood comes out first, but I can't ever do that because I put in 2ml of liquid and the plunger is too far back for me to grab and pull back
