I felt the poop pass through, went through the whole motion of defecating ( straining) , but when i looked down into the toilet nothing was there.

Sensation: Hi It's common to be able to feel your bowels contract internally as you're having a bowel movement. If nothing came out, you may be having trouble with constipation. You can try an over the counter laxative for more immediate relief, but I would recommend also increasing the amount of fresh fruits and vegetables in your diet. Hope this helps
