I'm also shocked at some of the responses you are getting. We had a 3 year infertility battle before I got pg the 1st time, only to m/c. It took almost exactly a year from the 1st time I got pregnant, for me to get pregnant with DD. Although a m/c is horrible for anyone, I think the struggle of trying so long to get pg only to lose it, may make a m/c even harder for those of us who have had that experience. Like you, I didn't know if I would ever be lucky enough to have it happen again. Hang in there and don't give up. 35 isn't old. I do agree with the posters that said that maybe your DH and family didn't say anything because they did not want to put a damper on your DD's birthday or upset you. I think you should talk to your DH about how you are feeling. He may even be wondering why you did not acknowledge the date yesterday. Maybe he just thinks you didn't want to talk about it, or you would have brought it up.
To be fair, the OP didn't initially state that she was having fertility issues. There is a big difference between having a m/c after having a hard time getting pregnant, and having an early m/c when you have no issues. I have a friend who had a m/c at 8 weeks. She had used her last frozen embryos, which resulted in a pregnancy. I was so sad for her, and it took her a while to get over it. After having 2 babies in 2 years (irish twins), my sister had 2 (very) early m/c's, and she was annoyed, not sad (she wanted a winter baby, ended up with a spring baby). It depends on the circumstance, and the person.
Honestly, I can't even remember my nieces and nephews birthdays - I'd never remember a due date.

I know how you feel, and words can not express anything that can make you feel better. It's just a very emotional thing. I am blessed to have 4 healthy children. In between DD11 and DS9 (children #3 and #4), I lost one in my 12th week, just past that first trimester mark. I was devestated, as was DH. I miscarried the day before DD11's 1st birthday, and my due date was Mother's Day. Not only do I shed my tears on Halloween (the day I m/c), but Mother's Day is not the happiest of days either because it should be a birthday celebration. We don't make a fuss of Mother's Day, and DH understands. It's been 10 years, and I still grieve. Not nearly like I did the first year, but I take my moment, shed my tears, and pray for my child in heaven. DH remembers when he sees me in tears and hugs me. He's more sensitive than most, but I don't think he would remember if it wasn't for me. No one else in the family remembers, and that's okay.
