I'm so very sorry that you're going through this Stina_Cake. A miscarriage is such a sad and gut-wrenching thing to happen in your life. It does sound like you have a wonderful DH and support from work and family. I wish you all the best for a rainbow baby soon.
I'm going through it myself at the moment, had a D&C two weeks ago. I was 11 weeks with a blighted ovum. Still coming to terms with everything, slowly feeling better about things, but still do have bad days.
One thing I have learnt is that you have to be kind to yourself, and do whatever is best for you in your healing.
If that means taking some time off work, or missing out on a social event or occasion when you're not feeling up to facing people, then do it. Put yourself and DH's feelings first. I was feeling guilty about taking a couple of extra days off work after my d&c when I was feeling physically okay but I was an emotional mess and someone pointed out to me that people take more time off work for a cold or gastro. That put things in to perspective for me, and taking a couple of extra days made me feel so much more balanced when I did go back.
And allow yourself to grieve, it's such an upsetting time, and no one can tell you how long you should or shouldn't be sad for, it's so personal.
Oh SuttonToBe, I remember you from the August thread, we were due around the same time. I am so so sorry to hear about your loss. I had the same feeling the other day, I would have had my NT scan and could have announced my pregnancy by now. I have a family member who is due a week after I would have been, and has just announced her pregnancy. I think I'm going to find all her milestones really hard reminding me of what we have lost.
Good luck for your wedding! Crossing my fingers for a sticky honeymoon baby for you.
