Could this be a precursor to labor?

About 3 days ago, I started getting loose bowels (totally not normal for me) and the last night it turned to diarrhea. I slept horribly (moreso than normal). Well, I woke up feeling awful, like I wanted to just crawl into bed again. I had breakfast and then threw up. I've been laying around nauseous until I threw up again.

The only other weirdness I noticed is an increase to my CM (that started when the loose bowels did. My BHs have been getting painful as well.

Should I assume this is a bug or something more?

I'm not sure but my OB told me dehydration can cause contractions/crampiness.  Try to keep hydrating and see if BH calms down.

I had loose bowels during contractions - like I was having contractions and stomach problems and thought it was something I ate, then when I went to the bathroom I didn't feel better. I delivered the baby about 24 hours later - I had contractions all day.
