I'm not sure where to post this so hopefully this is the right place. I have never met my dad and don't really know anything about him apart from his name and therefore I have no health information or genetic history from that side of the family. I have thought regularly about this over the years and have been terrified of carrying a cancer gene or condition I have no idea about. Now I am pregnant with my first baby and my anxiety is going into overdrive, I could be a carrier of anything and I don't know. Do I need to talk to the midwife about this? Should I request any tests? I've considered speaking to my mum about this and trying to find out some information but I don't want to upset her. Should I try and track him down on Facebook? Just to be clear I have no interest in a relationship with him it would be purely for medical history.
