Hi there,
The best chances of conceiving are from some 5 days before until 1 to 2 days after ovulation. A sperm can live for up to 5 days in the uterus and that is why a woman can get pregnant if they ovulate within 5 days after intercourse. Get a prenatal checkup done and ask your doctor about prenatal vitamins like folic acid. Take a healthy nutritious diet and adequate rest. Stay away from stress and exercise daily. If you do not conceive in next few months you and your partner may need evaluation for infertility. Hope it helps. Best wishes and regards!
