Since you stopped taking Duphaston (dydrogesterone) four days ago, you can generally expect your period to start within 3 to 7 days, though it can sometimes take up to two weeks for your body to adjust. The negative pregnancy test 16 days after ovulation is a very reliable indicator that you are not pregnant. Your body is just taking a little time to respond to the drop in hormone levels after stopping the medication. Take a deep breath, try to relax, and if your period doesn't arrive within 10 days, please reach out to your healthcare provider.

The combination of dydrogesterone (Duphaston), progesterone (Susten), and human chorionic gonadotropin (Fertigyn) injections is a standard and effective regimen to support early pregnancy and help prevent miscarriage. Mild vaginal spotting at five weeks can be common as your body adjusts, and hormone injections can sometimes cause minor spotting due to increased blood flow to the cervix. While this is often harmless, please contact your obstetrician promptly to get checked, as keeping them informed is always the safest step.

Typically, your bleed will start within 2 to 7 days after your last dose, as your hormone levels drop. The mild cramping you are feeling is a very common sign that your period may be on its way. Since it has only been two days since your last dose, a negative pregnancy test is reassuring, but it might still be slightly early. I suggest waiting another 3 to 5 days. If your period still hasn't arrived by then, please take another pregnancy test or consult your healthcare provider. Rest assured, this delay is a normal response to the medication.

Yes, it is indeed possible to experience early cramping or even start your period while still taking Duphaston (dydrogesterone). This often happens as your body adjusts to the hormonal changes, or if there is a slight shift in your natural cycle. Please rest assured that this is a relatively common occurrence and usually not a cause for alarm. However, if the cramping becomes severe or the bleeding is very heavy, it is always a good idea to reach out to your doctor for personalized guidance.

After finishing Duphaston (dydrogesterone), it can take 7 to 14 days for bleeding to begin. If it doesn't occur, the most common reasons include an early pregnancy, low estrogen levels (meaning the uterine lining was too thin to shed), or hormonal fluctuations from stress or thyroid issues. As a first step, I gently recommend taking a home pregnancy test. If that is negative, please consult your doctor. They can run simple blood tests to check your hormone levels and may recommend an ultrasound or a tailored hormone therapy to help restore your body's natural rhythm.

At five weeks, the gestational sac can often appear low in the uterus but can naturally move upward as your pregnancy progresses and the uterus grows. Duphaston (dydrogesterone) is commonly prescribed to help support your pregnancy and manage bleeding. This early ultrasound finding does not mean you need to terminate the pregnancy. It is highly recommended to continue your medication as prescribed and schedule a follow-up ultrasound in one to two weeks to check on the development. Please stay in close contact with your doctor, who will guide you safely through this.
