False alarm

Last night, I went to the hospital because I was having contractions every 5-6 mins for an hour. They monitored me and IV'd me. Unfortunately, the contractions spaced out to 10 mins and no cervical changes. They offered morphine but declined and decided to just go home. So frustrating and a bit disappointing. I just hope my body knows what to do this time around (second baby). They told me to drink lots of water...which I am already doing. I drink plus 64oz of fluids a day and pee my brains out. Doesn't seem to really help contractions.
