Yep, that means you're o.k. If you pull back like that and blood enters than you need to withdraw and try again.
BTW - You can strike veins and get a little blood drip in the pin head - even before aspirating. Aspirating pretty much confirms it. So no need to pull back too far. Just enough to see either clear (tiny bubbles) fluid or blood.
Yup Listen to what Warrior said, and some times even when you aspirate, you might get a little blood when you pull out the needle after an injection.
I've been told by several not to pull back too hard or for too long or you can get very sore
Pull back very gently... the first time you hit a vein you'll understand why.. it feels like pulling water into the syringe it's so easy to pull the plunger. So just give it a tiny little pull and if it doesn't easily glide back filled with red you're good to go!
