@acerbaby I'm sorry you are going through this. Big hugs. I haven't had a miscarriage but my daughter was stillborn at 20 weeks. I'm currently 27 weeks pregnant.
We lost our DD2 in December last year and for a long while there was no way I could contemplate having/trying for another one, but loosing DD2 left a huge hole in our lives and to help us try and heal TTC again was the only answer and it has helped in a way, but there is a lot of stress with the subsequent pregnancy after loss, all the girls in here know it thats why its so good to have them to chat with as they know what the fears and anxieties are being pregnant after loss.
I think just take your time and look after yourself in this awful time and see how you feel in a few weeks or maybe a few months. I think the need for another child will come back to you, in time.
