Sounds like the exact symptoms I had and I was diagnosed with internal hemmoroids. I had dripping and blood clots and it was painless, I suffered this on and off for years.
Sitting on the toilet too long and straining can irritate the internal hemms making them bleed quite badly.
A simple checkup at the docs will put your mind at rest and there are various cures for them.
Diet change and not sitting and straining on the toilet long are self cures.
I had them banded at the doctors office and have not bled since.
I unfortunately sit on the toilet too long and I am addicted to reading on the toilet, I panic when I can't find something to read when I need a poo
