Take all tje time you need hun. You will need time to grieve this baby, and also time to grieve for the brother or sister you so wanted to give your little boy. I really really hope for you that you'll have answers, and that one day you'll have your rainbow. Baut as we discussed in my journal, this is so painful, time and energy consuming that it is totally normal to need a break from ttc or stop completely.
I also hope that the next steps will be as kind to you as possible.
