With Polycystic Ovary Syndrome, periods can be irregular, and medicines like Deviry are often given to induce a withdrawal bleed, which usually occurs after completing the full course and stopping the tablets, sometimes taking up to 7-10 days to start. Since you had unprotected intercourse 3 weeks ago, a negative home pregnancy test is reassuring, but for complete certainty, you can repeat the test after a few days or get a blood test (beta-hCG). For now, continue the medication exactly as prescribed and wait for a week after finishing the course; if you still do not get your period, or if you develop symptoms like severe pain or heavy bleeding, you should revisit your gynaecologist for further evaluation (such as an ultrasound or hormone tests). Avoid taking additional medicines on your own, and try to maintain a healthy lifestyle, as PCOD-related irregularity is common but manageable with proper care.

Taking two doses of Deviry (10 mg) within a short gap is unlikely to cause serious harm in most cases, especially as a one-time mistake, but you may experience mild side effects such as nausea, dizziness, headache, drowsiness, or temporary hormonal effects. Since this medicine is a hormone, it is not intended for use without prescription (and is usually prescribed for women), so no further doses should be taken, and you can simply monitor yourself for any unusual symptoms. If you feel severe dizziness, vomiting, or any concerning reaction, it is best to consult a doctor. Otherwise, no specific treatment is usually needed, and the effects should settle on their own.

Continuous bleeding for 10 days with severe abdominal pain needs careful medical attention, and Deviry (a progesterone medicine) is often prescribed to help control abnormal uterine bleeding by stabilising the uterine lining, so it can be effective if taken as directed. However, since your symptoms are significant, it is important to follow up with your doctor to confirm the cause (such as hormonal imbalance, fibroids, or other conditions) through appropriate tests if not already done. Do not stop or change the medicine on your own, but seek urgent care if bleeding becomes very heavy (soaking pads frequently), pain worsens, or you feel dizzy or weak. Along with medication, rest, good nutrition, and iron intake may help if there is blood loss. Overall, Deviry can help, but proper evaluation and monitoring are essential to ensure the right treatment.

Mild side effects like low mood, headache, and drowsiness can occur with Deviry because it is a hormone-based medicine, and these symptoms usually improve on their own after completing the course. To manage them, make sure you get adequate rest, stay well hydrated, eat regular, balanced meals, and avoid activities like driving if you feel drowsy; simple pain relief like paracetamol may help with headaches if needed. Try to reduce stress and maintain a regular sleep routine, as this can also improve mood. However, if your symptoms are severe, persist beyond a few days after stopping the medicine, or you experience significant mood changes (like worsening depression), it is important to contact your doctor for advice, they may adjust the dose or suggest an alternative. Do not stop or change the medication on your own without medical guidance.

A missed period for 40 days with a negative pregnancy test is often due to a hormonal imbalance, which can be triggered by stress, weight changes, excessive exercise, or conditions like Polycystic Ovary Syndrome or thyroid problems. In many cases, it is not serious, but it should be evaluated if it happens repeatedly. Treatment depends on the cause. Your doctor may advise lifestyle changes (healthy diet, regular exercise, stress management), check hormone levels, and sometimes prescribe medicines like progesterone (e.g., Deviry) to help induce a period. It is also a good idea to repeat the pregnancy test if there was any recent risk, or get a blood test for confirmation. If your cycles continue to be irregular or absent, a proper medical evaluation is important to ensure the right treatment and prevent long-term issues.

After taking an emergency contraceptive like i-pill, it is common for your next period to be delayed or irregular due to hormonal changes, and since your pregnancy tests are negative, pregnancy is unlikely (you may repeat a test after a few days if still unsure). Deviry is often prescribed to induce a withdrawal bleed, and the usual course is taken for about 5-10 days (the exact dose and duration should be followed strictly as advised by your doctor), after which periods typically start within a week of stopping the tablets. It is important not to self-adjust the dose, and if you still do not get your period after completing the course, or if you develop symptoms like severe pain or heavy bleeding, you should consult your doctor for further evaluation. Maintaining a regular routine, managing stress, and monitoring your cycle can also help normalise periods over time.
