I tried my first injection today and noticed there was fluid on the surface of my skin after. I was nervous about trying it, didn't know how hard to push, and got surprised/scared when it went off because the sound and the force were more than I expected. I jumped so bad that I ripped away the "pen" before I think it was truly done. Have others noticed this same residual fluid? I'm afraid that because I jumped it ended up not doing it right.
