I'm 43, with 4 kids and to be blunt really don't think I could cope with any more. They're gorgeous, wonderful and totally knackering! Yet finding out this morning that my blood results (from a chance conversation with my gp last week) are back and that I need to book a routine 'fertillity appointment with my gp' has totally floored me! Nothing else has made me feel so instantly old and past it! I feel like I'm suddenly on the shelf - a has been with no use. I'm really scared!
