This morning I threw up really bad im 29 weeks and on my way back to the room my whole body temp just dropped and I cant stop shaking and I had a very very painful cramp where the baby is...then 2 minutes later another and then another again. They hurt pretty bad and I dont know what to do. Should I go to the e.r.? My doctors office isnt open yet. Is it normal to have b.h. contractions three or so in a row?
