You go 7 months at a time without period after having baby and trying to conceive for almost 1 half yrs how likely is it what could be causing missed this long?

There are several possible reasons why you may have missed your period for 7 months while trying to conceive for 1.5 years. Some potential causes include:

1. Postpartum Amenorrhea: After giving birth, it is common for women to experience a period of amenorrhea (absence of menstruation) due to hormonal changes and breastfeeding. This can last anywhere from a few weeks to several months.

2. Breastfeeding: Breastfeeding can suppress ovulation and menstruation in some women. This is known as lactational amenorrhea and is more common in women who are exclusively breastfeeding and have not yet introduced solid foods to their baby.

3. Hypothalamic Amenorrhea: Stress, excessive exercise, low body weight, and certain medical conditions can disrupt the normal functioning of the hypothalamus, a part of the brain involved in regulating hormones and ovulation. This can lead to missed or irregular periods.

4. Polycystic Ovary Syndrome (PCOS): PCOS is a hormonal disorder that affects ovulation and can cause irregular or absent periods. It is characterized by the presence of multiple small cysts on the ovaries, elevated levels of certain hormones (such as androgens), and often associated with symptoms like acne, excessive facial or body hair, and weight gain.

5. Thyroid Issues: Thyroid disorders, such as hypothyroidism (underactive thyroid) or hyperthyroidism (overactive thyroid), can interfere with menstrual cycles and cause missed or irregular periods.

6. Pregnancy: It is important to rule out the possibility of pregnancy if you have missed your period for an extended period. While breastfeeding, it is possible to become pregnant even without having a regular menstrual cycle.

If you have concerns about your missed periods and difficulty conceiving, it is recommended to consult a healthcare professional for evaluation. They can perform relevant tests, such as blood work, hormone tests, or imaging studies, to determine the underlying cause and recommend appropriate treatment or interventions to help you conceive.
