Periods don’t always mean you're not pregnant. You might feel tired, need to use the bathroom more often, or have sore breasts due to hormonal changes. If you're unsure, it's best to take a pregnancy test to confirm rather than guess.

According to the dates you've given, it is improbable that pregnancy would result from the action on September 8th. As it was after your period, the probability of you becoming pregnant is not very high. The first indicators of pregnancy can be such as missed periods, nausea, fatigue, and breast tenderness. If you notice any of these symptoms, it is a good idea to take a pregnancy test to be sure.

It is normal for girls to not have­ their period some time­s. The big reason is often change­s in hormones. Stress, losing or gaining weight fast, and too much e­xercise can all cause misse­d periods. Living a healthy life and not be­ing stressed can help. If you are­ worried, it is good to talk to someone you trust, like­ a parent or the nurse at school.

The chances of achieving pregnancy four days before your period are low. The changes that you are suffering from may result from hormonal changes or other causes. Tiredness, soreness of breasts, rise in vaginal discharge, and nausea can occur during monthly periods. The reason for sweating, chills, and excessive appetite may be due to other factors like stress, diet, or sleep.
