anxiety in new pregnancy.

Today I am so anxious. In a way I've been ignoring my pregnancy, trying everything to keep my mind from thinking about it . I don't want to get my hopes up like the last two times. Last December I got pregnant with my second baby and lost he/she at 8 weeks 4 days, I got pregnant again with my third child in august and again lost him/her but this time at 4 weeks 2 days. I'm currently 8 weeks 3 days and this is probably the most difficult week I've had to deal with so far. I haven't had an ultrasound since week 3-4 when baby was just a sac and I question everyday if my baby has grown at all as my first mc was a missed miscarriage and baby had passed two weeks prior to when I started miscarrying. I expect everyday to start bleeding but am surprised if I don't. Sorry for babbling, I feel alone and I feel like I'm unlucky and this won't work out for me. I just want to hear some mommas who have success stories or even are sharing the same feelings as me.
