Susten 300 contains progesterone, a hormone that helps prepare and support the uterine lining for a pregnancy. Using progesterone after ovulation is a common and generally safe approach to support early pregnancy, especially if you have had a prior miscarriage. However, because timing is critical and dosing must be tailored to your specific cycle, it is very important to discuss this with your gynecologist before starting. They can guide you on the exact timing to ensure it is safe and effective for you.

At 28 weeks, a cervix of 2.6 cm is slightly short, but your risk of early labor is being actively managed. Your prescribed medications are highly effective: Susten SR (progesterone) helps relax the uterus, while Tidalan (isoxsuprine) prevents contractions. Shelcal HD and Uprise support your nutritional needs. Staying on strict bed rest, drinking plenty of water, and avoiding physical strain are crucial to help prolong your pregnancy, and contact your doctor immediately if you experience severe pain, fluid leaking, or bleeding.

It is FDA-approved and widely used globally. In India, doctors frequently prescribe it to support early pregnancy and prevent complications. While it is highly beneficial and generally safe, like any medication, it can have mild side effects like drowsiness. Indian physicians prescribe it based on clinical need, but it is always best to discuss your personal history and any concerns about side effects directly with your doctor to ensure you feel completely comfortable with your treatment plan.

While incorporating nutrient-rich foods like avocados, nuts, and leafy greens is wonderful for your overall health, they cannot replace Susten SR 300 (progesterone) during early pregnancy. Your doctor prescribed this medication to ensure your body has the precise, stable levels of progesterone needed to support and protect your developing baby. Natural foods cannot provide these high, therapeutic doses. Please do not stop or change your medication without consulting your obstetrician.

Both early pregnancy and your oral progesterone medication (Susten 400) can cause fatigue and dizziness. Progesterone naturally relaxes the body, and taking it orally can sometimes make these side effects more noticeable. Because the symptoms of early pregnancy and progesterone side effects overlap so closely, it is difficult to distinguish between them right now. Please try to rest, stay well-hydrated, and rise slowly from sitting to help with the dizziness. The most reliable way to know for sure is to take a home pregnancy test once your period is late.

Accidentally taking a double dose of your progesterone (Susten) for 10 days is very unlikely to harm you or your baby at 7 weeks of pregnancy, as progesterone is a natural hormone crucial for supporting pregnancy. You might experience temporary, mild side effects like extra sleepiness, dizziness, or breast tenderness. I recommend returning to your originally prescribed daily dose of 200 mg starting today. Please contact your OBGYN to let them know about this minor mix-up so they can guide you on your next steps.
