It's scary, I completely agree - the sadness and the fear make ttc a lot harder. Much more difficult to muster any motivation, let alone 'romantic' feelings to get on with dtd. I'm currently trying to muster up the motivation to start trying again...
To be honest, I usually go with the head-in-the-sand approach, trying not to think about what has happened and even less about what could happen and just get on with it (soooo romantic !).
However, while it all might seem really grim now, you might feel more relaxed in another 6 weeks. Try to take comfort in the fact that statistically, you have everything on your side that next time, it will all be fine! But easier said than done, I know.
At the end of the day, remember why you are doing this - to have a baby... And keep reminding yourself again and again to stay focussed.
Sorry if that's not very helpful, it's a tricky one! Good luck!
