Small baby, so overwhelmed

Cena-Marie
Back in October my husband and I found out that our little girl has a 2 vessel cord. (She only has one vein and one artery instead of two arteries in her unbiblical cord.) So I was classified as high risk and sent to a specialist. (Eventhough I am text book health perfect blood pressure, no gestational diabetes, heat rate perfect, only gained 8-10 pounds. Etc.) I started having growth scans done every 4 weeks at the specialist and normal appt at the OBGYN which ment I was at doctors appt every 2 weeks. The first specialist appt was a little scary finding out that little one was at the 8th percentile in growth. She is supposed to be in the 10-99th percentile in growth. Since she was behind they wanted to do another scan in 4 weeks. Nov. We had our 2nd scan and she had jumped to the 15th percentile. Doctors and us were excited that she was showing progress. The next scan in Dec. showed she was then at the 6th percentile. At that time we were told to come back twice a week for nonstress test and dopplars to ensure she is getting adaquet blood and nutrition flow. And we would do another scan in 3 weeks. If she could stay above the 5th percentile they would let me go to 38-39 weeks before they would enduce. If she fell below the 5th percentile then they would take her at 36-37 weeks. So back and forth to the doctors I went. At each appt I was told everything looked great and kept hearing she seems to be a happy baby. Last Wednesday we went for a follow up appt. And we found out that she is now in the less then 1 percentile in growth and they want to proceed with the 36-37 week plan. So I am to continue twice a week testing with a final growth scan on Jan 26th. On top of it all she is breech and they want to do a c-section which scares me. They said we would try turning her with a version if she does not turn on her on by then. If she refuses to turn or stay turned then c-section it is. Ugh! I wanted a natural birth and now it is like everything Is spinning out of control and it is so hard being the planner I am. I have gone from everything looks great to this wirlwind situation. Not only is this a factor but they are not expecting her to be more than 5 lbs at birth. They are leaning more toward 4lbs or so and possible stay in NICU. So full term premie sized baby. I love her so much that I am scared to death. Please keeps us in your thoughts and prayers as we take everything day by day. I just want to curl up in a hole and cry because of the fear. I know God's got this but it is still hard. Thanks!
