With a negative beta-hCG test on day 36, pregnancy is highly unlikely. Your delayed cycle is likely related to your PCOS and thyroid disease. Regarding Susten (progesterone), it is completely normal that you haven't started menstruating yet. A withdrawal bleed typically begins 2 to 10 days *after* you finish the medication course, not while taking it. Please complete your prescribed dose. If your period doesn't start within 10 days after your last pill, please consult your gynecologist to discuss the next steps.

When you stop taking vaginal progesterone (Susten), your body's progesterone levels naturally drop. This sudden decrease signals your uterine lining to begin shedding, which often starts as light brown spotting or bleeding. This is simply older blood and is a normal response as your body resets its natural cycle. If the bleeding becomes unusually heavy, is accompanied by severe pain, or continues for more than a few days, please reach out to your healthcare provider for a quick check-up.

Yes, using Susten 200 mg (which contains the hormone progesterone) vaginally after an IUI procedure can help support your chances of conception. Progesterone plays a vital role in preparing and thickening the lining of your uterus, making it a warm and welcoming environment for a fertilized egg to implant and grow. Providing this extra hormonal support is a very common, reassuring step to help give the embryo the best possible start. Continue to follow your doctor's guidance.

It is completely normal to feel a bit anxious while waiting. After finishing your five-day course of Susten 300 (which is progesterone), your period typically starts within 2 to 10 days. Sometimes, it can take up to 14 days for hormone levels to drop and trigger the bleeding. Since your pregnancy test is negative, please try to relax and give your body a few more days to adjust. If your period does not arrive after two full weeks of stopping the medication, I gently recommend reaching out to your doctor for further guidance.

A progesterone level of 5.1 ng/mL confirms that you have ovulated, which is a very positive sign, though it is slightly low for supporting a new pregnancy. Since you are trying to conceive after a miscarriage, your doctor prescribed Susten 400, which is vaginal progesterone. This medication works by supplementing your natural hormone levels, helping to thicken and prepare the lining of your uterus. This creates a secure, nourishing environment for a fertilized egg to implant and grow, giving your body the extra support it needs in the early stages. Please continue to use it as directed.

Yes, if you are not pregnant, you will still get your period. After you finish your 10-day course of Susten (progesterone), your hormone levels will drop, which typically triggers a withdrawal bleed (your period) within 2 to 10 days. Since you ovulated on day 20, the best time to take a home pregnancy test is 14 days after ovulation (around day 34 of your cycle), or a day or two after completing your Susten course. This will give you the most accurate and reliable result.
