2 consecutive miscarriages. Frustrated and scared.

I've had 2 consecutive miscarriages, one last October when I was 7 weeks pregnant and the second now in March, when I was really at the beginning. Didn't even know I was pregnant. Doctors have examined me and said there is nothing wrong. I am really healthy, my uterus and eggs are perfect, I was just unlucky and this is not unusual. But I am really afraid and scared. Does anybody had the same experience with a happy ending? Any hidden problem? Something to tell or suggest me do? Thanks.
