preterm labor

Olivia
Tuesday I was admitted for preterm labor, Thursday night they said they were going to stop trying to stop my contractions and they gave us the option to
Go home or stay and be monitored so we went home and tonight I am having a ton of contractions. No other symptoms have changed, maybe a little more nauseous but idk when I'm supposed to become concerned because I've been contracting all week. Anyone have experience and know when you're supposed to come back in. ??
