Duphaston and Nidagen are both progesterone supplements used in pregnancy to support the uterine lining and help maintain pregnancy. The main difference is that Duphaston is a synthetic progesterone (dydrogesterone), while Nidagen is a natural form of progesterone, often given orally or vaginally. Both are effective, and neither is clearly better; the choice depends on your doctor?s preference, your tolerance, and specific clinical needs.

Your current treatment plan is beautifully designed to help you succeed. Siphene (clomiphene) works to stimulate your ovaries to grow and release healthy eggs, while Duphaston (dydrogesterone) helps prepare your uterine lining to support a pregnancy. Qcar forte, which provides essential nutrients like levocarnitine, helps improve egg quality. Many women with PCOD successfully conceive and deliver healthy babies with this exact medical support. Stay positive, continue monitoring your progress closely with your doctor, and take things one step at a time.

While a negative pregnancy test 12 days after a missed period is highly reassuring, there is still a very small chance of pregnancy if ovulation occurred later than usual. Before starting Duphaston (dydrogesterone) to induce your period, it is safest to absolutely confirm you are not pregnant with a blood HCG test. Since you are 42, irregular cycles can also sometimes point to normal hormonal shifts, such as perimenopause. Please consult your gynecologist to get a blood test and discuss if Duphaston is the right, safe option for you.

After finishing dydrogesterone (Duphaston), it is very common for your period to take anywhere from 3 to 10 days to start. Since it has only been five days, your body is likely still adjusting. The mild left-sided cramping you are experiencing could be due to your ovaries reacting to the fertility medication (Goodova), normal premenstrual changes, or even early pregnancy. I recommend waiting another 2 to 3 days. If your period still hasn't started, a home pregnancy test is a great next step.

Since you ovulated on day 17, you are now 16 days post-ovulation. A home pregnancy test is highly accurate about 14 days after ovulation, so you can absolutely take a test today on cycle day 33. Sometimes, stopping dydrogesterone (Duphaston) can slightly delay your period, but a test now will give you a reliable result. I am sending you my very best wishes for a positive outcome.

To help understand these occurrences and your irregular periods, especially after a D&C, a thorough evaluation is key. We typically recommend checking for uterine issues (like scar tissue) using an ultrasound, testing for hormone imbalances, and screening for clotting or genetic factors. Duphaston (dydrogesterone) is prescribed to help regulate your cycles and support your uterine lining. Please work closely with a reproductive specialist who can guide you through these tests and create a personalized plan to support your future health and pregnancy goals.
