Yes, your pregnancy can absolutely still be viable. At 8.3 mm, the gestational sac is still very small. Typically, we do not expect to see a yolk sac or embryo until the sac measures over 10 to 20 mm. Because you have irregular cycles, you are likely just much earlier in your pregnancy than estimated. The fact that the sac is growing and you have no pain or bleeding is very encouraging. Continuing your prescribed progesterone and human chorionic gonadotropin (hCG) support is important. Your doctor will likely schedule another ultrasound in a week or two, which should give you a much clearer and more reassuring picture.

Since it has been about 17 days since your IUI, a negative urine test is likely accurate, but it is not absolute. Sometimes, a blood pregnancy test is needed for definitive confirmation. Since you have finished your Duphaston (dydrogesterone), you can expect your period to start within a few days. I gently recommend contacting your fertility clinic. They will advise on a blood test to be sure and discuss the best next steps for your journey.

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.

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.

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.

Yes, even a faint line on a home pregnancy test typically indicates a positive result. Fertomid (clomiphene) and Duphaston (dydrogesterone) help support ovulation and early pregnancy, and they do not cause false positives. Mild lower abdominal cramping can be a normal sign of early pregnancy or a result of your recent fertility treatments. However, because the pain is persistent, it is very important to contact your doctor. They can perform a blood test and an ultrasound to safely confirm your pregnancy.
