After posting and getting great advice I have taken the plunge and have ordered the blue horizon bloods the 12 one. However, I have come down with a virus, razor blade throat, aching ears and a slight fever. I also had my first period in 9 months (I am at peri menopause, I think). So as you can imagine I feel even worse than usual. I am concerned that if I have my bloods done while I am unwell it will show up slightly different to my normal self. Should I wait an extra week or so. In the bigger picture I have been out of sorts for years so a couple of weeks more does not really matter.
