You have to put all of it in I'm afraid Belfa! I was a bit daunted when I saw it but if you get enough flesh to inject it into, its fine! If you are skinny you can sit up to try and 'pinch more than an inch'! I don't have much fat on my tummy so did that so that the needle only went into fat and it didn't hurt at all. It was just like a scratch going through the skin then you don't feel it going in any further cos there are no nerve endings further below!
I think you should take the clomid but forgo the scans for this cycle, we went on holiday for my 2nd clomid cycle but it was fine because the previous month scan showed just one dominant follicle. I think its more of a problem if you had 4 or 5 large follicles last time. (It saved us £450 too!) Can you leave a message with the clinic letting them know and ask them to contact you with an appointment to get another prescription when you get home?
