Penny, I'm in a very similar situation to you... our first embryo transfer worked, and a scan at 6 weeks and 5 days showed a heartbeat... two weeks later, after some bleeding, we went in for another scan - the heartbreak of that empty screen is devestating and something that I think will stick with me forever. My FS wouldn't run tests, but believes it was just a random chromosomal problem that meant that embryo would never make it. He said there's no reason to believe that any of our three remaining embryos would have the same problem. We consulted with another FS to actually get some tests done, and he also said that if it was a random chromosome problem, there's no reason to believe the other embryos would have the same problem.
My miscarriage was in July - It was really rough at first, but things slowly got better in time. Bad days still happen (I'm having one today, in fact), but they do become less frequent. I do believe that waiting until you are emotionally ready is necessary - don't rush yourself. Much better to wait a bit longer and be sure you are ready than face it too soon and leave yourself in a much worse emotional state because of it. We're looking at starting again within the next few weeks, and the break (and some councelling) has done me a lot of good.
I wish you luck when you do decide to start again, and know that there are many women here who share your pain, and know what it's like to lose a much longed for and loved baby.
