Dear Lulu, I am sorry to hear you had to experience a M/C and you have been having a hard time thinking about ttc.
As you mentioned it is only very recent so don't be too hard on yourself so soon. You need to take time to grieve and deal with what you have just gone through.
I know my situation is not necessarily the same but I do understand how you feel about being scared to ttc after a loss. We lost our daughter at 39 weeks and I was really afraid to try again as I felt I couldn't protect my child, and I felt I should have been able too. I know this is not even logical cause really you can't, but at the time you are so all over the place emotionally its hard to know what you feel.
We had to wait the usual 3 months as it was a normal labour and almost fullterm which was a good thing as it gave me time to deal with my grief and to try and understand everything in my head. Greif is a strange thing and it makes you think silly things too.
Give yourself some time to adjust to what has happened and you will know when you are ready to ttc again.
I found initially my fear of loosing another baby was greater than my need for another baby, but then in time this changed and my need for another baby was greater than my fear. So I new that it was what I wanted to do. In time, I am sure in your heart you will know when the time is right.
I hope that knowing you are completely normal helps just a little bit!!
Good luck and when you are ready I hope you have mych success in ttc again.
