Has anyone used gonal f injections and they have worked?

Also i would like to know if anyone had problems injection them self? It took me an hr to do it last nite i kept putting the needle in but couldnt push it far enough in i was to scared but when i did push it in it wasnt right to the end of the needle but i injected it anyway and neva felt anything is this normal? Also how lond did you have to inject urself for on the 1st cycle. Thanks for any answers x
