I am heartbroken. I am currently experiencing my second miscarriage this year. My first was in April at 5 weeks and this was at 6.5 weeks. I don't understand. The docs say that it is still probably due to chance but there must be something wrong as I had a baby 18 months ago and I conceived her no bother and had a very difficult long labour. Could a section have damaged my womb, or could this be hormonal? Does anyone have any similar experiences to share. I feel so alone and unhappy.

No I don't but I am sorry for your loss. You should be grateful for the child you do have and of course find out what the problem may be. I understand this must be very difficult for you and your hormones must be going crazy but try and stay strong.
