Is brown spotting common in 4 days of missed period?

It is possible to experience brown spotting around the time of a missed period, but every woman's body reacts differently and your experience might vary. Brown spotting can be related to hormonal fluctuations and changes that can occur early in pregnancy, or it could also be a sign of pre-menstrual symptoms. Here's some information to consider:

* Implantation bleeding: Some women experience light spotting or implantation bleeding around the time of implantation of the fertilized egg in the uterine lining. This usually occurs around 6-12 days after ovulation and may last for a few days.

* Hormonal changes: Fluctuations in hormone levels during the menstrual cycle, including those related to pregnancy, can cause changes in the uterine lining and lead to spotting or bleeding.

* Premenstrual symptoms (PMS): In some cases, brown spotting before a missed period may be related to PMS, which can include various physical and emotional symptoms.

If you're experiencing brown spotting along with other pregnancy symptoms, such as nausea, breast tenderness, or fatigue, it's a good idea to take a home pregnancy test to confirm whether or not you're pregnant. If you're still concerned or the spotting continues for more than a few days, it's advisable to consult with your doctor for proper evaluation and guidance. They can determine the cause of the spotting, rule out any underlying issues, and provide you with appropriate care and recommendations.
