In early pregnancy, even a few days' difference in conception can affect what is visible. Duphaston (dydrogesterone) is a hormone that supports your uterine lining, helping to secure and protect your pregnancy, especially given your history. For precautions, please rest as much as possible, avoid heavy lifting or strenuous activity, and try to stay relaxed. If you experience severe cramping or heavy bleeding, contact your doctor immediately.

At 29, your age is a wonderful advantage, and your husband's 60% sperm motility is excellent, which is highly reassuring. By using clomiphene citrate and an hCG injection, your body is being guided to ovulate. Having intercourse around 40 hours after the trigger shot is very well-timed, and starting Duphaston (dydrogesterone) on day 16 provides excellent luteal support. Typically, this protocol offers an encouraging 15% to 20% chance of pregnancy per cycle, which is very close to natural conception rates. You have followed the steps perfectly.

Yes, undergoing an IUI and taking hormone medications like Duphaston (dydrogesterone) and Susten SR (progesterone) can definitely delay your period. These progesterone medications are prescribed to support the lining of your womb. By keeping your progesterone levels high, they prevent your period from starting, even if pregnancy hasn't occurred yet. Typically, if you are not pregnant, your period will start a few days after you stop taking these medications. I highly recommend taking a home pregnancy test or consulting your doctor for a blood test to get clear answers.

After stopping Visanne (dienogest), it can sometimes take a little time for your period to return as your body readjusts. However, because you are experiencing severe left leg pain, it is very important to have this evaluated by a doctor promptly to rule out any circulation issues. Please contact your gynecologist or seek medical care right away to ensure you are safe and supported. They can also advise you on the best time to start Duphaston (dydrogesterone).

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.

It is generally safe, and often recommended, to take hormone therapy (such as progesterone or combination hormones) for a few months after treatments. These help stabilize your hormone levels, regulate your cycle, and protect your ovaries and uterine lining. Your most important next step is to consult your fertility specialist or gynecologist. They can evaluate your current hormone levels and safely tailor your ongoing treatment plan.
