Thanks for your ideas.

Christy- that is great to hear that you did hear the heartbeat at 12 weeks, do you know if that is fairly common or not?

Sorry susan, you are right, it isn't radiation risk, I went back to my book and apparently there is research indicating that there may be subtle effects on neurological status, blood cells, immune system and genetic makeup for the baby. It sounds like many studies are not in agreement. That is a good idea re if not happy with doppler to then go to u/s.

I totally know my due date, as I know my cycles really well ( we have been trying for a while) and about 3 days post conception I get breast changes.

I am planning on having a 19 week u/s and we will probably find out lots more then, so still not sure if I need a 12 wk one.

It is sometimes hard to trust my own intuition that everything is fine and we will have a beautiful healthy baby, so that is what I am really trying to practise at the moment!
