So miserable. Can't believe this is happening.

I'm 36 weeks & 4 days. Started having contractions at 1:30am that came on strong and hard. Went to the hospital at 4am when they still hadn't let up. They checked me and I was at 3cm & 70% effaced. Also baby is stationed at -1. After 5 hours of walking, loosing my mucus plug, and having my bloody show, along with more contractions I hadn't dilated any more so they just sent me home. I'm so discouraged. Is labor coming soon? The contractions are still coming but lighter now.. should I assume that nothing is coming of this now? So disappointed and just want to cry, I really thought this was it.. maybe my water will break soon or something? Please pray my baby boy will be born soon ❤️
