Are these air bubbles safe to inject? There's 1 on top & 2 small ones at the bottom. I tried flicking them but they wont rise to the top.

Also, tips on how to draw a dose with no air bubbles without sacrificing medicine? I saw a youtube tutorial that says to draw 2x your dose then, while the needle is still in the vial, push the air bubbles back in until you get your dose. It's supposed to not waste any medicine. I tried it and it works sometimes but sometimes, i still get bubbles like these ones.
