Ella - I'm sorry I wasn't on earlier to give some encouraging advice! How are you going now? I can understand why you are worried, but stay positive and try not to think about it too much. I have heard of people getting a dopler machine (have no idea where), not sure if you hire or buy, that can hear babies heart beat. There might have even been a post on BB about it.

Please let me know how you are going and like Relle said, if you need to chat or email, just send me an email
