Anyone else???

So I'm just curious... I'm about 17 days away from my due date... This morning I woke up with onset diarrhea and spent about an hour and a half on the toilet... I also vomited... However, I have no fever and felt completely fine after I got it all out of my system... I have also been having decent cramps on and off all day... I have heard that diarrhea and vomiting can be a sign of impending labor... Has anyone else had similar experiences? This is my first baby, so I'm not real sure what to expect
