I wanna know if I could be pregnant or not...My stomach has gotten bigger and I have stretchmarks...I have never gotten them before in my life and I don't think my mom has them...or maybe she does. What I want to know is what is the difference between a pregnant woman's stomach and a woman who is overweight...If there is a difference, is it likely when you bend that your stomach doesn't stay round...like I don't know how to explain it...I guess curls? Please let me know.
