What can i drink for my stomach?

My stomach is bloated. I felt a lil constipated when i went to the bathroom. I got a lil out but i feel and look bloated still. And i feel that i need to get more out. Is there a juice like a natural laxative that i can use? I dont like using the medicine laxative my mom wont let me(bad past). Ive tried plum juice but it didnt work for me and it tasted nasty. Any other juice? Or do i just drink water? Thanx!
