I had a micro preemie at 24 weeks due to a uterine infection that caused preterm labor. how likely am i to have another preemie?

Varies: If it was truly due to an infection and that infection is treated and cured, you would be at no higher risk than usual.However, if there were other contributing circumstances, like early cervical shortening, any abnormalities of uterus, then the risk could be a lot higher. It's an excellent thing to talk to a maternal-fetal medicine specialist about and what you can do pre-pregnancy to prevent.
