Is it just me or is it hard to find that bubble? I keep looking and turning the thing upside down and see a tiny speck but don't know if it's a bubble ir what.

What does it mean if there really is no bubble and what can happen?

Have you tried to flick the syringe (or pen) a little bit with your index finger to see if it comes to the top?

I don't remember if I had never had a bubble in mine before. I took it for 4 years. Anyway, I don't know that it matters if there is one in there or not. I think the whole bubble thing is bad if you are injectiong something into a vein, because air can go into the heart or something... (i think), but I don't know about just the subq injections if it matters or not.
