Both Duphaston (dydrogesterone) and Susten (micronized progesterone) are widely used and considered safe to support early pregnancy. While micronized progesterone is FDA-approved in the US, dydrogesterone is approved and trusted globally, though not currently marketed in the US. Dizziness is a common side effect of progesterone. To help manage this, try taking your doses right before bed or resting for a short period after your morning dose. Staying well-hydrated and rising slowly from sitting can also help. Please consult your doctor to see if your dosing schedule can be safely adjusted.

After surgery to remove tissue buildup and cysts, your body needs time to heal. Some pain and bleeding fluctuations are normal as your tissues recover and hormone levels stabilize. Dydrogesterone (Duphaston) is a highly effective hormone therapy that helps prevent this tissue from returning by regulating your uterine lining. Most reassuringly, dydrogesterone will not harm your future fertility. In fact, by keeping the condition under control, it helps protect your ability to have children when you are ready. Please share these symptoms with your doctor to ensure your recovery.

Dydrogesterone (Duphaston) typically takes about two to three cycles to establish a regular menstrual pattern. After completing a course, a withdrawal bleed usually starts within three to ten days, though it can sometimes take a bit longer as your body adjusts. Since your period is nine days late, I gently recommend taking a home pregnancy test if there is any possibility of pregnancy. If it is negative, please give your body a few more days, and update your doctor.

In the 8th month of pregnancy, you should not start or continue Duphaston 10 mg on your own unless your doctor has specifically advised it, as it is usually given earlier in pregnancy for hormonal support. It will not help with headache or back pain. For those symptoms, rest, hydration, posture care, and a safe pain reliever like Paracetamol (if suitable) are better options. Please consult your doctor to confirm whether you need to continue Duphaston and to evaluate your pain properly.

Since you recently stopped Duphaston (dydrogesterone), your body may just need a few days to adjust, as withdrawal bleeding typically starts within 3 to 10 days after your last dose. Your very first step should be to take a home pregnancy test to rule that out. If the test is negative, try to give your body a few more days to regulate. If your period still does not arrive within a week, please reach out to your gynecologist to discuss the next steps.

For progesterone support at 9 weeks with a history of miscarriage, standard protocol typically involves using either oral dydrogesterone (Duphaston) or vaginal micronized progesterone (Susten), but rarely both together. Combining them is generally redundant and not standard practice. Either medication alone is effective, so a single, consistent method is usually preferred to keep your routine simple and stress-free. I highly recommend discussing this with your OB-GYN.
