Hi Maggie519, maybe you and your husband can visit a doctor to get some tests done before you start trying. Those tests should be able to check if there is any DNA defect or potential problems for you two to have baby. It will probably minmize the risks as if you know there is a high potential to have a baby with problem then you may reconsider again. It will be better to have baby earlier because the older you get, the higher chance for complication or birth defects.
I am also just past 30 and trying now. Don't worry so much and go ask your doctor to get the right answer. Wish you all the best.
