Gave me a shock I can tell you, but not sure how worried I should be.
It's purple rather than red blood coloured IYSWIM and quite dark. I know it happens if you eat a lot of beetroot, but I can't remember the last time I did that.
Yesterday I ate shreddies with milk, a ham sandwich, banana and a Turkey dinner followed by Christmas pud. Today I've had boiled eggs with toast, a fresh fruit smoothie made with banana and a handful of frozen berries and a cold spread of bread, pate, smoked mackerel and cheese, followed by apple pie and ice cream.
Last night I had 2 glasses of red wine and 2 white wine, plus a coffee and today I've had a Lucozade sport drink. Other than that I've only had water to drink (and I drink a lot of that so wee usually very light).
I did a 10 mile run this afternoon, so feel tired, but not ill at all. It only started around 5pm today.
So, what can it be?
