how do u explain this reddish stool....

Bright blood means that it is 'close by' and dark blood means that it is coming from somewhere 'up the line'.
Or at least that is my rule of thumb.
What are you eating? Is it possible that it has some red colouring in it? (just asking because I had a panic attack yesterday when I emptied my pouch and the bowl was red. 3xs in a row it was a dark red. I have bleeding before so I recognise it immediately but I had forgotten about the red jujubies!).
Certain chewing gums with fruit centers, jelly candies, Twisters, beets, red grape juice, wine etc can all do that.
If you haven't eaten anything that has artificila or natural colouring in it then maybe a stool test is in order.
Have you spoken to your doctor about this? What does he say?
Can you go to any lab and have them take one or do you need an appt?

Are you sure it's blood? Like Sharon mentioned, Sometimes certain foods/drinks turn my stool a reddish color but it's not blood. Always startles me until I take a closer look.

The only red thing is a powder in my drink but I do that to take my vsl3DS at 9am. Possible that it stays in system till way later like that? I always thought things were out of our body in like 4-6 hours

Some things definitely take up to 24 hours to exit my body. I never would have thought it can take that long in the absence of a colon but it can.

My transit is 12-24 hours. It could be the morning drink responsible for it.

Also, anything strongly "fake" colored really affects stool color. I about died years ago after eating Fruity Pebbles: my stool was neon green.

To rule out or confirm something as the culprit, just eliminate it for a couple of days and see if it makes a difference. Dyes in one thing you consume can absorb into other foods. That is how it can take variable times to transit.
