It is generally expected for a gestational sac to be visible on an ultrasound around five weeks after your last menstrual period (LMP). However, every pregnancy is unique and there can be variations in when the sac becomes visible. In some cases, it may take longer for the sac to form.
Taking Duphaston (dydrogesterone) is often prescribed in early pregnancy to support progesterone levels and promote healthy development of the embryo and gestational sac. This medication helps create a favorable environment for implantation and growth of the embryo.
If your doctor has prescribed Duphaston for one month, it may be because they want to give your body additional time to develop the gestational sac before considering any further interventions or treatments.
It's important to remember that each woman's reproductive system functions differently and there can be various factors contributing to delayed or absent gestational sac formation. These factors can include hormonal imbalances or issues related to egg quality.
While it can be concerning if a gestational sac is not visible during an ultrasound, it doesn't necessarily indicate a problem with the pregnancy. It's possible that the sac may become visible in subsequent ultrasounds as your pregnancy progresses.
It is recommended to follow up with your doctor for further evaluation and monitoring. They will be able to provide you with more specific information and guidance based on your individual situation.
