I understand your concern.
And it’s my first privilege to pay attention and provide you with suggestions to relieve your discomfort/ worry.
As such there can be a variety of causes of missed periods like hormonal imbalance, weight gain, weight loss, PCOD, thyroid dysfunction, pregnancy to name a few.
With a history of irregular periods, your doctor may recommend a repeat urine pregnancy test for a precautionary measure.
Hormone fluctuations can occur due to changes in diet, changes in sleep patterns, exercise routines, stress levels, etc. It can also be caused by any new medications even over the counter supplements or any recent illnesses
Otherwise, if it would be negative again then your doctor may advise some form of progesterone to induce a period and further investigations like ultrasound, blood work like Thyroid function test, LH, FSH, etc may be advised for further diagnosis and management.
Track your basal body temperature (BBT) to assess if you're ovulating.
Track your cervical secretions to assess your fertility. You're most fertile when your mucus resembles egg whites, looking and feeling stretchy and clear. The more of this mucus you have, the higher your likelihood of getting pregnant. Ovulation is done when the mucus has thickened.
Try an over-the-counter ovulation test can assess when you're ovulating. That way you'll get an idea of when you should plan to have sex.
Maintain a healthy weight.
Avoid caffeinated coffee, tea, alcohol, and soft drinks (decaf is fine).
