Missing periods can occur for several reasons, including stress, changes in weight, or hormonal imbalances. Common symptoms to watch for include fatigue, mood swings, or changes in appetite. It’s essential to take a home pregnancy test if there's any chance of pregnancy. If the test is negative or if you continue to miss cycles, I recommend to consult a gynecologist. They can evaluate your health, discuss your medical history, and help identify any underlying issues. 

It's understandable to feel uncertain if your menstrual cycle is delayed. Common signs of pregnancy can include missed periods, nausea, fatigue, and breast tenderness. Various factors like stress, changes in weight, or hormonal imbalances might also lead to irregularities in your cycle. To determine if you are expecting, consider taking a home pregnancy test. Following that, it’s wise to schedule an appointment with a gynecologist for confirmation and to discuss your overall health. 

It's completely understandable to have concerns about the hymen, especially if you're not sure what to expect. The hymen can vary in shape and size among individuals, and a triangular appearance can be normal. Since your recent pelvic ultrasound showed no abnormalities and you have no symptoms like pain or unusual discharge, it is likely all is well. However, if your concern continues, don't hesitate to consult a gynecologist for a thorough evaluation.

It's great that you're taking steps to understand your treatment. When counting the 11 days for Duphaston, you should start from the first day of your last menstrual period. This means your counting begins on the day your period starts, and you take the medication on days 11 to 25 of your cycle. This medication helps regulate hormone levels, particularly if you experience irregular cycles or other related symptoms. If you're unsure or have specific concerns about your treatment, please don't hesitate to reach out to your gynecologist for personalized guidance. 

Agar aapki mahavari samay se zyada der se aa rahi hai, to iske piche kai karan ho sakte hain, jaise hormonal changes, stress, ya lifestyle factors. Aam symptoms mein mood swings, weight changes, ya fatigue shamil ho sakte hain. Major issues ki taraf bhi dhyan dena zaroori hai, jaise polycystic ovary syndrome (PCOS) ya thyroid problems. Aapko yeh samajhna chahiye ke yeh sab aam hai, lekin agar samasya khud se sudhar nahi hoti, to doctor se sampark karna achha hai. 

It's understandable to feel concerned about your missed period, especially with a history of irregular cycles. While protected sex reduces the risk of pregnancy, no method is 100% effective. Given your cycle history and recent changes in your body, stress or hormonal fluctuations could contribute to this delay. I recommend taking a home pregnancy test for peace of mind. If it’s negative and your period doesn’t start soon, consider consulting a gynecologist for thorough evaluation and personalized advice. 

It's understandable to have concerns about potential pregnancy. Since your girlfriend's period arrived on January 16 and was relatively normal, it’s likely she is not pregnant. The negative pregnancy tests further support this, but it's crucial to note that test results can vary based on timing and hormone levels. The back pain she experiences may be a regular premenstrual symptom. For reassurance, consider having her consult a gynecologist, who can offer personalized guidance and may perform a more sensitive pregnancy test if needed. 

It's understandable to be concerned about your missed period. Various factors, including hormonal changes, stress, or the influence of emergency contraception can cause menstrual irregularities. A negative home pregnancy test is reassuring, but since your period has not returned, it may be beneficial to consult a gynecologist. They can provide insights, perform necessary evaluations, and discuss possible solutions. 

Based on your detailed information, it is very unlikely that you are pregnant, especially since you have had regular menstrual cycles and negative pregnancy tests. The ultrasound conducted 13 weeks after the event further supports this. Cryptic pregnancies are rare and typically present with symptoms like missed periods, but you have had normal bleeding. If you remain concerned, it's reasonable to consult a gynecologist  to address any lingering worries. 

Based on the information provided, the likelihood of pregnancy is very low, especially considering regular menstrual bleeding and a negative ultrasound after 13 weeks. Cases where people remain unaware of pregnancy are rare and typically involve irregular cycles or specific medical conditions. Your negative urine test and ultrasound findings support the conclusion that you are not pregnant. However, if concerns persist, consult a gynecologist for additional reassurance and possible further testing.

Periods ka irregular hona aur delay hona kai wajah se ho sakta hai, jaise stress, hormonal imbalance, ya lifestyle changes. Jab aapne pregnancy test kiya aur faint line dekhi, toh ye indicate kar sakta hai ki shayad pregnancy hai, lekin result ko confirm karne ke liye test ko kuch din baad dobarah karna behtar hoga. Abhi aapko apne health par focus karna chahiye; sahi diet, exercise, aur relaxation se madat mil sakti hai. Agar periods nahi aate ya symptoms continue karte hain, toh please Gynecologist se milkar check-up zarur karein.
