I did all of my own. I am a bit of a control freak so wouldn't be able to cope with OH doing them. They are not that bad, esp gonal f pen, the needle goes in so easily. The tips I have are to vary the injection site but stay away from the area just below belly button, for some reason it's quite uncomfortable and it wasn't just me that thought it. You will be fine, the first one is the worst as you don't know what to expect xx
