I'm 26. Am I being silly? I'm not fat, I don't smoke, I do eat a lot of fatty foods, it doesnt run in my family, but there's a bulge in my lower left abdomen, I've been constipated for as long as I can remember.. low fiber diet. I poop like 3x a week. is that normal? The last 2 times my stool were shaped like crescent moons.. Like round on one side, flat on the other, but like they were forced flat.. Im 22 weeks pregnant.
