Early labor started and then stopped

Raquel • Mom to be
I spent last night at the hospital. I was contracting every 3-5min and had my bloody show. They checked me and I was 3.5cm dilated and baby's head was very low. This we're not BHs. They were very painful, I couldn't move (they even offered me Morphine! but I refused it), but since I didn't dilated more they sent me home. Now here I am, my contractions aren't close anymore. Such a big disappointment. I'm so achy and not feeling like I can go on like this for 3 more weeks 😭 
Has anyone have a similar experience?!
 
Ps. I'm not looking for 'baby will come when he is ready' or 'don't be so selfish' answers. Thank you!!
