Possible TMI, and I promise I am not a poo troll.
Yesterday evening I had a bout of diarrhoea, pale/whitish in colour. I've had this in the past with food poisoning.
This morning was a bit runny and pale again, and when I wiped I noticed what appeared to a a thin strip of bluish plastic, around 2 or 3 inches long on the paper...so somehow I must have ingested this without knowing 
What on earth could it be?
And perhaps that is why my belly hasn't been quite right over the last few days - because I ingested whatever this was. Thankfully no belly pain, but been feeling a bit nauseous today.
Any advice on what I should do?
