Blood in stool and when I wipe

Pre-warning: TMI 
So over the last year, when I've had a bowel movement occasionally there has been a tiny spot of blood of the tissue but as it was tiny and every time, I thought nothing really of it. 
The last two days I've had a lot more blood where the water in the toilet has turned pink and a similar amount to when you wipe on a period, I'm really worried but at the same time embarrassed to go to the doctors! 🙈 has anyone get any idea what it could be or how to stop it?
