I am in wk 2 of my cycle and went to do my Sustanon pin. I plunged the needle, then I did a slight retraction on the plunger to see if I was in a vein. I saw no blood in the syringe, so I injected. I pulled out the needle, capped it and then I saw blood at my point of injection. Not much, but I thought I would ask. Did I maybe just nick a vein? Because I did not see any blood in the syringe until after I pulled it out? Or did I just not retract the plunger enough?![]()
