Okay, so my dr called me a few days after my first appointment when I was 8 weeks, and tells me there may be a cyst in or on the baby's umbilical cord.. Have any of you ladies been through this? Does it just go away? I've read problems it could cause, and I'm prayin the cyst will just go away over time.
