Stillborn daughter jan 9 of 2013 and still can't getting pregnant.

Tabetha
I lost my daughter when I was 20 wks 5dys. I gave birth to a child that was not alive. After I lost my daughter almost three years ago I am wondering if anyone else have had problems getting pregnant. It has been almost tree years and I still haven't gotten pregnant again. My ex and I were trying to get pregnant for about 7 or 8 months after I lost her. And then the man I am with now, we have been trying for even longer than that and I still can't get pregnant. We never use condoms. We have sex every other day and we don't use any birth control. He always cums in me. But I still can't get pregnant and I just don't understand why. Any advice?
