Update

Joy here again...just got off the phone with a peaceful Karen - she really sounded great (and I know when she's trying to cover her anxiety - this was real peace!) She said they really are doing well emotionally - she said it must be because of the many prayers that you all are praying on their behalf!
Here are some more details:
She was on multiple drips earlier today...sugar water, magnesium (to stop any contractions, which she has not had any), and antibiotics to keep any infection away...and they have taken her off all of those at this point. She did get a steroid shot today to help develop Adalynn's lungs. They still have not seen the specialist at UAMS - she is expecting that they will see him tomorrow. The plan right now is for her to get another steroid shot for Adalynn's lungs tomorrow morning (Thursday) at 10:00, which will work for 24 hours. They will also do the MRI tomorrow to see if the placenta has grown into the uterus at all. Also, as of now Adalynn is breech. My understanding is that if they find from the MRI results that the placenta has grown into the uterus, they will do a c-section. Also, if Adalynn remains breech, they will do a c-section. They do not want to deliver Adalynn at this point - they'd really like to wait as long as possible. They're really going to shoot for a week to 2 weeks - ideally, they'd like for Karen to be 34 weeks, but Karen said they did not sound hopeful that that would be able to happen. They did another ultrasound today at UAMS and estimated Adalynn's weight at 3 pounds. Her heartbeat is great every time they check it, and she even had the hiccups today :) Karen has not dilated at all and is not in pain.
She couldn't stress to me enough how incredibly covered and loved they feel - it was so neat to hear it in her voice - it was true, humble gratitude for the incredible love they are being shown. They know our God has got this, and you can hear it in Karen's voice. They thank you, thank you, thank you for your love, support, and prayer...please keep it up! As you know, there is much to be prayed for. The Drs. are concerned for Karen because of her blood clotting issues, so along with a healthy Adalynn, please lift up Karen and her health as well.
She did also say that she will for sure have to stay at UAMS until Adalynn is delivered. It sounds like they (Drs. and nurses) don't even really know what the "next step" is...it sounds like it's a bit of a waiting game right now. So please pray for continued peace for them, and also please pray especially for Crist, Dane, and Ty - for them to really feel God's supernatural peace and comfort.
Thank you again for all your prayers...they are making a difference!!
