Seeing a normal heartbeat is an excellent and highly reassuring sign of a viable pregnancy. In early pregnancy, discrepancies in measurements, such as a yolk sac measuring at five weeks, are quite common and can simply be due to late ovulation or normal variations in early development. There are no specific medications or treatments to alter the size of a yolk sac. The most supportive step right now is to continue taking your daily prenatal vitamins containing folic acid. Your doctor will likely recommend a follow-up ultrasound in one to two weeks to monitor development. Stay positive, as a strong heartbeat is currently the most encouraging indicator.

A low-lying placenta is quite common in early pregnancy and often resolves naturally as your uterus grows. While it requires careful monitoring, there is no need to panic. There are no specific medications to shift the placenta's position. Instead, management focuses on pelvic rest (avoiding intercourse and heavy lifting) to prevent bleeding, alongside regular ultrasound scans. If bleeding does occur, seek immediate medical attention. In such cases, your doctor may recommend supportive treatments like iron supplements for anemia, or generic corticosteroids such as betamethasone if early delivery is anticipated. Most women with this condition have healthy pregnancies with proper care.
