Sent home from hospital too soon?

A little history on me…I have 2 boys and aM pregnant with my third. My 2 boys were both born at 34 weeks. Went into preterm labor with my last boy. I went into preterm labor at 28 weeks this pregnancy, and a magnesium sulfate drip stopped it. I’m 32 weeks today and have been cramping on and off for 12 hours. I started having contractions about 8 hrs ago. Went to the hospital, was given fluids, and discharged while still contracting because cervix hadn’t changed. Doctor checked my cervix and I’ve been bleeding a tiny bit. I get home, get in bed, and all the cramping is coming back. I hurt and I just want to sleep. Anyone have early labor start like this? With the cramping and contractions on and off?
