A single previous miscarriage usually does not change the medical management of your next pregnancy significantly. However, most providers will offer some additional monitoring for reassurance.
An early ultrasound at 6 to 7 weeks is often scheduled to confirm an intrauterine pregnancy and check for a heartbeat. Once a heartbeat is confirmed, the miscarriage risk drops to about 5 percent — which is enormously reassuring. Some providers will also check early hCG levels and progesterone levels.
If you have had two or more consecutive miscarriages (recurrent pregnancy loss), your provider may recommend testing before or during the next pregnancy. Tests may include karyotyping (checking both partners' chromosomes), uterine evaluation (ultrasound or HSG to check for structural issues), blood clotting disorder screening (antiphospholipid syndrome), and hormonal evaluation (thyroid function, progesterone). If you are classified as high-risk, you may have more frequent visits and ultrasounds throughout the pregnancy.
