Ah spider I'm so sorry for your loss.
Mine was Saturday just gone (from my first IVF treatment) so I know some of what you're feeling.
I've been so sad for the past 6 months. On Saturday, DH, DD and I went to a significant place and released white balloons. I'm not usually so airy-fairy but I felt I needed to mark the day somehow and it really helped me. I said some words to my lost baby whilst doing it and it has given me some solace.
I'm also 7.5 weeks pregnant now and I think that helped me get through the day.
I hope you find some way of making today easier for you and your partner.
