Premature

Has anyone had their little one 2-2 1/2 months early? If so what can i expect? Anyone get the steriod shots for babys lungs? I have placenta previa which has caused me to constantly bleed and be in constant pain. My doctor doesnt expect me to make it much past the next 5-6 weeks which means my baby will be born roughly 10 weeks early. Please any advice and experiences with preemies and what to expect.
