Im in week five of my 3rd cycle and last night the first night I injected it myself. I am terribly afraid of needles lol. On that note, I'd like to thank the people at this site for giving me the balls to "man up" as someone posted, and just do it myself. But anyway my question is this. Is it important to switch sides every injection? Currently im injecting it into my a** cheeks. If doesn't really matter I'll stick to doing it on the right side because I think it would be much more difficult doing it with my left arm.
