Why is my poop all thin like pasta?

Hi all, I wrote a question here about stools and now am writing another one, I got my stools tested for blood and it was negative, but now my stools have gone weird again, all thin and like pasta, i do have my period but is this normal?
Has anyone had this and it’s ok?
I’m starting to freak out about my bowels now.
Also my tummy feels not so good, like when you get the runs, that is how my tummy feels, so could i eaten something that my body doesn’t agree with to create thin like stools?
I also need to go poop and that’s the only thing that comes out and it’s freaking me out?
any help would be greatly appreciated, is it normal for our bodies to just do weird things sometimes?

Thanks
I’ve decided today i’m not eating to get out whatever it is that is in my gut – is this a wise decision?
