You could be right as I did do a few things wrong during the injection process. Since it has been about 5 years since I've ran a cycle I had forgot that I used to always use an 18 gauge needle to draw and then put the new needle back on just prior to pinning. I used the same needle with probably dulled the hell out of it and also I used a 1" needle instead of the 1.5" that I used to normally use. The last injection went fine but I did throw out that old gear just to be safe.
