Over the past few weeks I've noticed I look like I have a small bump.. almost like I look like a few months pregnant. But I know I am not. What's up with this?. I haven't gained any weight.. I just look pregnant. I'm almost 18 and wondering if this is normal? Any explanations maybe?

Any changes in habit, less exercise, no it is not normal to gain inches ( esp without weight gain)

Actually.. I have been working out. Which I have never done before. I don't know if that has anything to do with this.. . but yah I thought it was strange..

If you are absolutely positive you are not pregnant (NOT having sex at ALL, even with protection) then its possible that it is muslce tone building up. Are you spending a lot of time on your tummy area in your work out? Like crunches, obliques, aerobics, yoga, etc?
