kissmummy, I am feeling for you and know exactly what you mean about "feeling flat". And also the obsessing about non-existent prenancy symptoms - you poor thing!
Try telling yourself that without positive pregn test it would be IMPOSSIBLE to go on and have a baby at some point, so first and most important step done: you got yourself pregnant, congratulations! I believe in the power of positive thinking.
I felt robbed of the excitement of early pregnancy after 3 MMC (all early, thankfully!), but then enjoyed feeling the baby kick much more because I so appreciated having something tangelible (sp?) to let me know all was well.
Now have 3 boys...
You hang in there, do not waste nervous energy on being cross with yourself for feeling whatever way you are feeling, be kind to yourself and live one hour day at a time. Do lots of things to distract yourself if you can.
Does your local hospital offer early "reassurance scan" for woman with previous MCs? Do you have access to an "Early Pregnancy Clinic"? There is good evidence that v closely monitored ie scanned early pregnancies after MCs do statistically better - must be a happy relaxed mum is better than totally stressed out anxious one.
Time WILL pass, even if it feels like treacle.. Very, very best of luck!
