Why hasn't my period come since September 6?

Missing your period may se­em concerning, but it happens some­times. The iPill can affect me­nstrual cycles. Reasons include stre­ss, hormones, or being pregnant. Look for tire­dness and nausea - they could signal pre­gnancy. Taking a test gives clarity. 

Let me assure you that the chances of pregnancy from outercourse with protection like tight boxers are incredibly low. The bleeding you experienced from 3rd to 8th June may likely be withdrawal bleeding from the emergency contraceptive pill you took, which is a common side effect. Given that your last period was on 17th May, your cycle might be a bit irregular this month due to the emergency pill. You can expect your next period within the next few weeks. If you don't get it by then, a simple home pregnancy test can provide further reassurance.

During your pregnancy, you often have symptoms such as nausea, fatigue, and mood swings. These are due to the changing hormone levels. Stress and lifestyle can also affect it. It is very important to take care of yourself; a balanced diet and regular exercise can make your health better. This time brings emotional and physical changes for you, so it will be beneficial to talk to a professional. 

Give yourself time to heal and avoid activities that worsen the pain. Over the counter pain relief like also can help but take only as if prescribed by a doctor. Apply cold compress to reduce swelling.
