....please see username for my stance on this matter - bit embarrassed to be asking for thoughts really!
Over the past few days I have been passing what I refer to (inwardly!) as 'pellet-y poos'; I.e. like a scaled-up version of what rabbits and goats produce. Some of them are coated with mucus, and the final ones have some red blood too. I'm vegan and am on a diet, so assume I'm getting enough fibre and water; basically I am at a bit of a loss to explain this event 
The only recent change I can think of is that I've been avoiding things with gluten in (not on purpose; more an accidental effect of avoiding carbs); can you develop a sudden gluten intolerance aged 37?!
I had thought it was simply women's issues til now and thought little of it, but my abdomen is now aching slightly all the time and I'm a little worried. I'm also a bit gassy.
Any thoughts, apart from the (perfectly reasonable) injunction to see a healthcare professional? If anyone recognises these symptoms and can say "I had that, got checked and it was fine" then it would put my mind at ease. I will still go to a doctor though, don't worry.
