After a year and a half of ttc I found out last week I had a blocked fallopian tube. The consultant recommended ivf and advised because I already have a child I will need to pay for this privately. The part that worries me the most (I know this sounds silly) is the injection part right at the start. I was wondering if anyone could explain this further to me. I.e is it in a epi pen style or a big needle? Where exactly do we need to inject it? I'm not scared of needles I'm just don't know if I can inject myself.
