Injection

So I’m concerned, I just gave myself my weekly injection and when I pulled the needle out of my thigh, I started gushing blood! I use a 23g 1inch needle. Did I go through a vain? Is there anything I should be concerned about! Did I just waste my dosage? I’ve never bled more and a tiny little dot! Like it was a considerable amount of blood too! I’m frightened! Help!
