At 37, i had two miscarriages for my second child. does it mean if i get pregnant again my child will have down syndrome?

No: While most miscarriages are due to issues w/viability, there is no association between miscarriages and down syndrome, which is a genetic condition more closely linked to maternal age. Best to go see your family physician or OB for pre-conception counseling to determine your individual risk for trisomy 21. Testing can be done early in pregnancy to find out if your baby has health concerns.

No But...: It is certainly a possibility, but a higher probability that down's will not happen. No guarantees.

No, but still risk: Miscarriages are most commonly (about 70-75%) caused by an abnormal number of chromosomes in the pregnancy. Downs (3 chromosome 21s) is one of the most common chromosomes to be abnormal. Still, the risk of a live-born child with downs is about 1 in 217 (age 37) and 1 in 166 (age 38). If you have multiple miscarriages then see a specialist to discuss testing. Best wishes.

Risk is elevated: As a mother's age increases, the risk of having a child with Down syndrome increases. You can address this with you OBGYN. If you become pregnant, there is a new blood test for Down syndrome which is non invasive compared to amniocentesis.
