It sounds like you're experiencing secondary amenorrhea, which means the absence of menstrual periods after having had them previously. There are several possible reasons for this condition after childbirth:

• Hormonal changes: After giving birth, especially if breastfeeding, hormone levels such as prolactin can remain high, which may suppress ovulation and menstruation.
• Postpartum complications: Conditions like thyroid dysfunction or pituitary gland issues (e.g., Sheehan’s syndrome) can affect menstrual cycles.
• Stress and lifestyle factors: Physical or emotional stress, significant weight changes, or excessive exercise can disrupt menstrual cycles.
• Use of certain medications: Some hormonal treatments or contraceptives can influence menstruation.

Since you mentioned no periods since 2015 and 2017 after childbirth, it is important to evaluate your hormonal status and overall health to identify the exact cause.

Next steps:

• Consult a gynecologist or an endocrinologist for a thorough evaluation.
• They may recommend blood tests to check hormone levels (like prolactin, thyroid hormones, FSH, LH).
• Imaging studies such as ultrasound or MRI might be needed depending on initial findings.
• Treatment will depend on the underlying cause and may include hormonal therapy or other interventions.

If you have been prescribed medications like Primolut-N (which contains norethisterone, a synthetic progestogen), it is used to regulate menstrual cycles but should be taken under medical supervision.

Please seek personalized care from a specialist doctor to address your condition safely and effectively.
