Contractions

I went to the hospital at about 8am ( i am 35 weeks) for contraction pains and what not that I've been having since about 5am this morning. I was hooked up to monitors to confirm that I was having contraction that were 2-3 minutes apart that were getting stronger. The whole day I stayed at 3cm dilated & 50% effaced --even though the contractions got to a good 7 on the pain scale. Around 3:30pm (after 11 hours of this) I was given a shot of morphine and gravol and sent home. contractions have since stopped all together. Maybe baby will come soon???
