are you sure you are having a m/c?
i know that sounds silly but my friend was told she had blood in her uterus, had bleeding on and off for over a week and when she went back for a scan they found a heartbeat and she now has a gorgeous little girl.
i totally understand how you feel about the worries etc and never having another child. they are thoughts i have every day. you are right not to jump into ttc if your relationship isnt great right now and that this was an oopsy and im sure when the time is right you will get pregnant again.
its never easy wether you are trying or not but i wanted to send you

and i will keep you in my thoughts and prayers.
please keep us posted
