TMI need advice. bleeding

Hi last week I had a spout of upset tum and again Saturday.

Ive been up since 3am today being sick and projectile runs.

sorry in advance, but at one point I was pooping and had to be sick, so for off to be sick and noticed blood in my sick.

I turned round to clean up and dark blood was on the floor dripping from my bum....

after I cleaned I had a wee which was also blood.

now do I ride this out as a good bug. or does anyone have any advice..

I've been burping and there eggy which I think means gastro???
