Hi @Pinkcloverss
I am the same as JennyD above, it wasn't a problem. My first was with my Onc and then he was happy for my GP to administer the rest.
They have to be regular and mine was every 4 weeks x 26 so it took 2 years.
My GP always used a local first and he would alternate each month, left and right abdomen. I found the left side I would have a funny tummy for a couple of days and the right was fine! I think my body was still wanting to cycle and this injection said No you don't!!
Honestly you will be fine, I think it is more scary when these things are suggested and you don't know enough about it!
In the grand scheme of everything I went through this was okay! Make sure the appointments are regular. I always made the next appointment before I left so I wouldn't miss!
Take care and best wishes as you navigate your way through treatment and a good outcome!
