I went for my 21week scan today and they have referred me to a consultant- after an internal scan and said that I have a blood vessel on the wall of my cervix which would mean a c section. They have said I won’t see a consultant until 28 weeks so I won’t know for a while. I just about got my head around this but then they began telling me to phone the hospital if I have any slight sign of bleeding- how worried should I be about this ? Anyone had similar? I don’t really understand the whole thing 
. Thanks in advance for replies - not sure if I am being a nervous Nellie!
