34 weeks, and feeling "weird."?

All of a sudden today, I've been feel very nauseous, and queasy. Flu-like symptoms, and had a loose bowel movement, but no puking. I just feel tired, and wore out. I suppose it's normal considering I'm heading towards the end, but it also feels like it could be a sign labor is near, or I'm just over yzing the situation. This is my second baby, so it could be more likely for me to go earlier then the full 40 weeks, right? I'm just stressing.
