Ugh..advice please

Hi mommas

Ok so I'm 36 weeks 3 days. Yesterday I was having contractions, that were about 5 mins apart, but they eventually stopped. Well today since earlier this morning my back and stomach has been cramping now stop. I threw up yesterday and haven't been able to eat anything today. It hurts very bad when BG move, but I do feel her moving. The stomach and back cramps have been coming and going and I have pressure. I just feel really really bad and out of it. Have anyone experienced this and actually been in labor or went soon after? BG has been very very active today and anytime she moves it causes stomach and back cramps. I don't want to to to L&D for nothing but I cannot shake this feeling at all... TIA
