I went for my 39 week appointment and had an internal exam. She said that from the opening I am 4 cm dilated but on the inside I am more like 1-2 cm. What does that mean? Anyone else told something similar?I had a membrane sweep done and she said that she didn't think it would be too long before the baby arrives. My first daughter was born 4 days after her due date so fingers crossed this baby is the same if not quicker!
