34 wks 2 days and in premature labor?

Sara
I've been contracting since noon went to the hospital around 1 when they were 7 minutes apart. After being there for 2 hours they let me go because I wasnt dilating just having some annoying and some hard contractions. They told me I'm in the beginning of premature labor and that my daughter is weighing around 6 pounds and 19 inches. But to go home and rest and let me body do its thing. But here I am going on 7 hours and the contractions are starting to get worse but still bare-able. Can this put the baby in destress? I'm so stressed I could cry right now! They told me unless my water breaks or if they get so bad that it takes my breath away there isn't anything they can do.
