Babies born early

Kaylen

I don't know if this counts as a baby question or if I'm posting in the right group idk where to ask this. But I am 27 weeks 5 days and have been having spotting and contractions but very far apart. I saw the OB Wednesday and because of this she scheduled another appt for Monday for an extra ultrasound just in case. But does anyone know what the rate is for babies surviving if they come this early? As of right now she is 2 lbs 4 ozs and I'm worried she is just gonna be so tiny if she comes too soon I'm so worried 😟
