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.

It is very common to feel a bit anxious when your cycle doesn't go exactly as expected. Typically, Duphaston (dydrogesterone) is prescribed for 3 to 6 cycles to help regulate periods. After finishing a treatment cycle, your period should start within 3 to 10 days. A slight delay after your second cycle can be normal as your body adjusts to the hormone. However, since a delay can also indicate pregnancy, I gently suggest taking a home pregnancy test. If it is negative and your period is delayed by more than two weeks, please consult your doctor to discuss your next steps.

It is very unlikely that you are pregnant if you experienced a normal period after completing your course of Duphaston (dydrogesterone). This bleeding is typically a sign that your uterine lining has shed. The dizziness and stomach cramps you are feeling now are quite common and are likely related to normal hormonal fluctuations or your menstrual cycle itself. However, because early pregnancy bleeding can sometimes mimic a period, the most reassuring step is to take a simple home pregnancy test. Please rest, stay hydrated, and consult your doctor if your symptoms persist or worsen.

Duphaston (dydrogesterone) is prescribed for seven days to ensure your body receives enough hormonal signal to trigger a reliable withdrawal bleed once you stop. Shortening the course to five days may reduce its effectiveness, meaning your period might not start as expected. For the best and safest results, it is highly recommended to complete the full seven-day course exactly as your doctor prescribed. Please consult your healthcare provider before making any changes to your medication schedule.

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.

A temperature of 98.7?F is perfectly normal and expected, as progesterone naturally raises body temperature. Localized pain from progesterone (Susten) injections is also very common because these injections are oil-based. To ease the discomfort, try applying a warm compress to the area. However, if you notice spreading redness, swelling, or warmth, let your doctor know. Your regimen of dydrogesterone (Duphaston) and progesterone tablets is safely supporting your pregnancy.
