How were you feeling the days leading up to birth?

I know it's a little early for me, I'm 36 weeks. I went to L and D because I was bleeding and having contractions. I was dilated to a 2 and they monitored me for 3 hours and sent me home. The next day I lost my mucus plug, and it was weird because when I got up I just randomly vomited out of nowhere too,  and that was about 2 days ago. Ever since I have been having menstrual pains in my back and the more I move around the more it hurts. Did anyone feel this way before they went into labor? Stories? :)
