Im having lower abdomonal pain and cramping off and on. could i have a bowel obstruction if i poop but its small and hard and difficult to pass?

Not likely: Generally, with a bowel obstruction you won't pass stool or flatus, you will have a distended abdomen and nausea and vomiting. More likely you are just constipated and you may have an Irritable Bowel Syndrome.
