Failed IUI

I tested this morning and it was negative. I was hoping first day of spring, a new beginning. That idea was shot to hell. This was our second IUI. Our first ended in a miscarriage at 8 weeks. We have been trying since 2006 to have another baby. We have had during this time a miscarriage, a stillbirth, another miscarriage, a blighted ovum and now another failed IUI. And I'm not getting any younger. I feel like life hates me for some reason. Why does it have to be so hard. I try so hard not to be bitter but it is just seeping into me slowly. My heart just hurts so much right now. I have to suck it up and go to work and put on my "I'm just nifty" face. I know I will break into pieces when I see my pregnant co-worker. Facing pregnant women is the hardest next to infant. Life just sucks.
