Curly - I am really sorry. I do understand what you are going through, although every person is different and reacts differently. The important thing now is to take good care of yourself. After I had my m/c in September I took things really easy, including a full 3 weeks off work, and we booked a 2-week holiday about a month after it happened. Of course nothing takes the pain away, but it did help me.
MrsMcJr - sorry to hear about it. Again, every person is different, so you are the only person that can work out what approach to the situation is best for you. In any case, as you are asking for people's experiences, I'll share mine, although it may not be what you need/want to hear. But of course your situation may be completely different, so please don't let this make you feel negative. Also, it is encouraging that that they gave you a 50/50 chance, because in my case they didn't.
In September, I had a scan because I was bleeding at 9 weeks and they told me the foetus was not more than 5 1/2 weeks and no hb was detected. They asked me when I had taken the pregnancy test- and when I said it was at CD29, they said it was unlikely I had had a late ovulation because at that point it would probably not have been positive yet (although they can't be certain, I think). They booked me for a scan the following week saying not all hope was lost, because dates could be wrong. But from the way they were talking to us, it was rather obvious they already thought I was most likely having a m/c and were trying to prepare us for the worst. In fact, the m/c happened 3 days later.
I am happy to hear that there are cases when the dates had been wrong - and I really hope it is what is happening to you and you'll have good news for us next week. Good luck.
Of course I am now worried about myself too, and will definitely try to get a scan in the next 2 weeks (am now at 6 weeks). I am not sure it works for everyone, but my approach now is that pregnancy is complicated, and that it's better to be informed, and know about things that can go wrong - although that doesn't mean one should spend their time worrying. On the contrary, being positive is clearly better - but positive in a realistic sort of way, if that makes sense.... If it's any help, from my experience and that of many friends, it seems to be really easy to get pregnant after a m/c and most people have a successful pregnancy next time.
