I've had a miscarriage befire and we've been trying again for the past year could something be wrong?

Maybe. See a REI MD: Two miscarriages is 'recurrent miscarriage'. You still have a chance of healthy pregnancy, but most couples get pregnant in a year of trying. See a reproductive endocrinology and infertility md to get checked out: we test your ovarian reserve (egg supply), look for hormonal problems, blocked fallopian tubes, problems with your uterus, sperm problems in your partner, and offer miscarriage testing.
