In the tanning bed i felt a hard mass moving around and i could push on it. When i put my hand on it, it felt like a heart beat. I cant even feel my own heart beat as well as i felt this. It was huge. I had my friend feel it and she put her hand on it and her hand moved as so the beating kept on. Her hand went up and down. it has moved to the left and right upper and lower side. I read that it would be my kidney but it feels like a heart beat. I am worried could i be pregnant?
