Big hugs Melnel, I hope your GP is able to put your mind at ease a little, and I think seeing her sooner is a good idea if you can.
I agree with what the others have said, don't doubt yourself for a moment. If anything, doctors tend to err on the side of caution so if they thought there was even the tiniest possibility that your baby might have been viable they would have waited to give things time to develop.
I don't know much about how the system here works these days, I was horrified that a friend had to wait days to have a d and c after her wee babe died. I lost our last angel in Sydney and Royal North Shore were brilliant, I was lucky in that I had the d and c as emergency surgery due to heavy bleeding so there was no waiting or mucking around.
I do think tho that there is a lack of support and acknowledgement after the fact, I very much felt like after I had the d and c I was supposed to go away and forget about it all. They gave me some pamphlets as I left hospital and that was it.
Two places I found great support were
The Lost Ones, a brilliant NZ website for people who have experienced the loss of a baby, and also Nicola Miller-Clendon's book Life After Baby Loss which is available in th eOHbaby! online store as well as most good bookshops. I read it long after I had the gremlins as a review copy for OHbaby! and I wish, wish, wish I had read it when I first lost our angel, it is so practical, and made me feel like all the craziness I felt was normal.
Big hugs!
Emma
