Ok so just got done pinning my left cheek and and as I pulled the needle out I squirt a little bit of blood! Not much but enough to squirt out and land on my floor. I pulled back on the syringe 3o make sure I wasn't in a vein so my only thought is I might have went through one? Is this possible? Should I be worried? What the hell did I just do!? I have pinned many times (this is my 2nd week into my 2nd cycle both are 12weeks) please let me know.
