I am pretty sure I injected into a vein today. A couple hours ago, I preformed my shot as usual, but when I pulled out there was a lot of blood. I mean a LOT. Dripped down to the floor from my stomach. I also started coughing really badly while this was happening. I am pretty damn positive I hit a vein. I am okay now, though, my heart and breathing have calmed down. I just want to know if I should re-do my shot tomorrow. I have been on t for about 18 months and this has never happened to me before. I have had blood but not this bad.
