Emergency contraceptive pills contain hormones that commonly delay your period by a week or more, and your negative pregnancy tests are very reassuring. However, please wait and consult your healthcare provider before starting any previously prescribed hormone medication. Introducing additional hormones right now can further disrupt your body's natural cycle. I recommend waiting a few more days, repeating a pregnancy test if your period still hasn't arrived next week, and speaking with your doctor to safely plan your next steps.

It is quite common to experience changes in your bleeding pattern after completing a course of dydrogesterone (Duphaston). When you stop this hormone, your body undergoes a withdrawal process, and your natural cycle is trying to re-establish itself. Bleeding or spotting two weeks later can happen as your body adjusts, especially since you were treating irregular periods. However, to ensure everything is settling back to normal and to rule out any other causes, I highly recommend checking in with your gynecologist.

To help understand these occurrences and your irregular periods, especially after a D&C, a thorough evaluation is key. We typically recommend checking for uterine issues (like scar tissue) using an ultrasound, testing for hormone imbalances, and screening for clotting or genetic factors. Duphaston (dydrogesterone) is prescribed to help regulate your cycles and support your uterine lining. Please work closely with a reproductive specialist who can guide you through these tests and create a personalized plan to support your future health and pregnancy goals.

Since you had unprotected sex, the most important first step is to take a pregnancy test, as four missed periods could indicate pregnancy. If you are not pregnant, Duphaston (dydrogesterone) can indeed be effective in inducing a period by mimicking the hormone progesterone. However, because you have missed your periods for four months, it is crucial to consult your doctor before taking it. They will need to identify the underlying cause of the delay and prescribe the correct dose and schedule safely for you.

Light, dark brown spotting four days before your expected period is quite common. It represents old blood and is not necessarily your period; it could be implantation bleeding or a minor hormonal fluctuation. Duphaston (dydrogesterone) is prescribed to support your uterine lining, making it more welcoming for an embryo to implant and sustain a potential pregnancy, especially after an IUI procedure. Please continue your medication as directed and take a home pregnancy test on your expected date, or reach out to your fertility clinic for a blood test.

After stopping Duphaston (dydrogesterone), it is very common for your period to take about 2 to 7 days?and sometimes up to 10 days?to arrive. This delay happens because your body needs a few days to adjust to the drop in hormone levels. Your mild cramps are a promising sign that your period may be on its way. Since your pregnancy test was negative, I suggest waiting another 3 to 5 days. If your period still hasn't started by then, it is a good idea to repeat the pregnancy test or contact your doctor for a quick check-in.
