Get a prenatal checkup done and ask your doctor about prenatal vitamins like folic acid. Stay away from
stress and exercise daily. If you are still unable
to conceive contact your doctor. In that case you and your husband both may need evaluation .The common causes of infertility are blocked tubes, ovulation dysfunction, hyperprolactinemia, thyroid disorders, PID etc.Sperm motility disorders and decreased sperm count are male causes of infertility. Hope it helps.
