Oh whiterose, I'm so, so sorry to hear of your loss.
Please do not worry about whether your reaction is 'normal' - I don't think there is a 'normal' response to miscarriage. Although, unfortunately, miscarriage is something many, many, women experience, each individual pregnancy loss is a unique life-changing event for that woman (and often their partner too). I think everyone just copes the best they can and there are no rules.
It must have been terribly difficult waiting a whole month to find out if your pregnancy was viable and perhaps, as you say, you did some mental preparation during that time? Alternatively, perhaps you had to mentally 'switch off' from your emotions a little to enable you to carry on functioning during that wait? Perhaps, at this time, you just need to focus on your physical recovery and your emotions will 'catch up' later?
From personal experience, my feelings about my miscarriage and how well I am coping has varied over time. Initially I was sort of in shock, then devastated, then not too bad, and now, as what would have been my due date looms, I am struggling again.
Things that helped me in the early days post-miscarriage were reading the threads in the mumsnet miscarriage section, reading some miscarriage poetry (made me weep buckets but really helped) and buying a lovely memory box to put all my pregnancy related stuff in.
Lots of hugs to you x
