I had my first real check up today. I'm 8 weeks with my very first baby and due at the end of march(for now) they said everything looked great except I have a cyst on the umbilical cord that they say they don't know much about, so I may have to go somewhere else for furthure tests. Does anyone have experience with this? I know it's a rare thing, like 1 in 100 but If I don't ask I won't know right? I'm a little nervous about that but all my other emotions are so happy and excited. When I saw the heart flutter on the screen I cried. It feels just a little more like reality now. I'm still in shock it finally happened after 2 years of trying.
