Irregular menstrual cycles and hormonal imbalances can be a source of concern for many women, especially when they are trying to understand their reproductive health and future fertility. Based on your description, it seems that you are experiencing significant irregularity in your menstrual cycles, with periods occurring approximately every one and a half months. This can be indicative of an underlying hormonal imbalance, which is often assessed through blood tests measuring various hormones, including Follicle Stimulating Hormone (FSH) and Estradiol (E2).

From your blood test results, an FSH level of 4.52 mIU/mL and an Estradiol level of 34 pg/mL were reported. FSH is a hormone produced by the pituitary gland that plays a crucial role in regulating the menstrual cycle and stimulating the growth of ovarian follicles. Estradiol, on the other hand, is a form of estrogen produced primarily by the ovaries and is essential for the development of the female reproductive system and secondary sexual characteristics.

The interpretation of these hormone levels can vary depending on the phase of your menstrual cycle when the blood was drawn. Since you mentioned that your period started the day after the blood test, it is likely that the test was performed in the follicular phase of your cycle. In this phase, FSH levels are typically lower, and Estradiol levels can also be on the lower side, especially if ovulation has not occurred.
Regarding the concerns raised by the two different doctors about your Estradiol level, it is important to note that normal Estradiol levels can vary widely depending on the individual and the specific phase of the menstrual cycle. While some sources may suggest that Estradiol levels should be above 200 pg/mL for optimal reproductive function, this is not a strict rule, and levels can fluctuate significantly.
The absence of ovulation, or anovulation, can lead to irregular menstrual cycles and may be a contributing factor to your current situation. Anovulation can occur for various reasons, including hormonal imbalances, stress, significant weight changes, and underlying medical conditions such as thyroid disorders or hyperprolactinemia.
You mentioned that you have undergone abdominal ultrasounds that ruled out polycystic ovary syndrome (PCOS), which is a common cause of irregular cycles and hormonal imbalances. This is reassuring, as PCOS is often associated with elevated androgen levels and other metabolic issues.
Given your concerns about fertility, it is understandable that you are anxious about your ability to conceive in the future. The prescription of ovulation-inducing medications by your doctor is a positive step towards regulating your menstrual cycle and enhancing your chances of ovulation. These medications can help stimulate the ovaries to produce eggs and may improve your chances of conception.

It is also wise to wait until your menstrual cycle stabilizes before undergoing further hormonal testing, as this can provide a clearer picture of your hormonal status. In the meantime, maintaining a healthy lifestyle, including a balanced diet, regular exercise, and stress management, can positively impact your hormonal health and menstrual regularity.

In summary, while your current hormone levels may seem concerning, they need to be interpreted in the context of your overall health and menstrual cycle. Working closely with your healthcare provider to monitor your cycles and hormone levels will be crucial in addressing your concerns about fertility and ensuring that any underlying issues are managed effectively. If you continue to experience irregular cycles or have further concerns, consider seeking a referral to a reproductive endocrinologist for specialized care.
