This is what Jen posted today on her facebook status:
I had a more accurate ultrasound done yesterday that shows about 5mm of cervix left. Not good. It also revealed that the mass in the placenta is most likely a chorioangioma (google it) which can cause additional serious complications since it interferes with the normal blood flow to baby. I don’t know what this all means but to just keep praying. Another ultrasound is scheduled tomorrow to check blood flow to baby’s brain.
Clearly we don’t know what this all means, but we know that God is good, and does what is good. Please continue to pray both for us and for our baby.
