i am currently using a little hcg during my cycle. i injected into my leg correctly, all the air out, asperated and all that. anyways I injected the hcg into my leg and as i was drawing the needle out of my leg a little blood got into the syringe. That's never really happened before i was checking to see if that was a big deal or if it was okay. If it is okay....is the hcg thats left in the syringe ruined or is it okay to use. Thanks.
