I didn't see any blood on the toilet paper, it was just in the toilet. It was just scary because it made all the toilet water red even though it didn't even look like there was that much blood in my actual stool.

Just wanted to say that even if it is blood, there are many possible reasons for this, some of them quite minor, like an infection or hemorrhoids. At your age, cancer would be very unlikely, though there are other things like ulcerative colitis and Crohn's that would probably need to be checked for, if this continues.

As others have said, just keep an eye on it. If it continues to happen over the next few days, then make an appointment with your doctor.

I have high blood pressure and drink and eat loads of beetroot. I can attest it absolutely turns your poo and everything else red! Given your age I reckon you're fine, but please get a specialist to check you out, just to be sure. 

There's a very very small risk of ut being more than just the beetroot you've eaten.I once had a major panic at how red my then baby sons nappy was, then I realised he had drunk a ton of blackcurrant Ribena and it had turned his poo red.

Keep an eye on it anyway just to feel more reassured.

Bless you x
