Hello dear, I understand your concern. In my opinion the miscarriage in first pregnancy might not always hinder for further pregnancy. There are various causes of abortion. And as per your information the miscarriage was due to genetic problem. Usually after miscarriage a gap of atleast 3 months is essential to plan for next pregnancy. As it was genetic problem you both the partners might need to undergo karyotyping to rule out any chromosomal anamolies. If you both are normal and that problem might not recur in furthur pregnancy. Also take folic acid tablet daily one starting from one month before planning the pregnancy. Nothing to worry.As most of the genetic anamolies does not recur . And abortion is the natural way of termination of abnormal embryo. So consider getting done karyotyping for both of you and start folic acid prior to planning of pregnancy. And a gap of 3 months is needed. Bus journey daily might not effect. But once the pregnancy is confirmed avoid physical strain. Hope this helps. Best regards....Dr.Srilatha
