Probably nec

My July baby was born on May 14,2018 at 29+5. She is twenty eight days old. Things seem to be going pretty good. Until the nurse practitioner came in and told us our baby girl passed blood in her stool. They did an x-ray and they seen a spot that they are watching. They said they would do an ultrasound in the morning to see how it is. But they are taking her off milk for now and giving her antibiotics through the iv. If it is that, they said it would be for ten days. I’m so worried and scared for her. Ive read so many horror stories on this. Please pray for our baby girl🙏
