I understand your concern. Irregular periods often indicate ovulation issues, which can make conceiving difficult. After five years of trying, it is crucial to consult a fertility specialist or gynaecologist rather than self-medicating. Common underlying causes like Polycystic Ovary Syndrome (PCOS), thyroid disorders, or hormonal imbalances must be diagnosed first. Depending on your evaluation, a doctor may prescribe ovulation-inducing medications (such as Letrozole or Clomiphene) or Metformin if PCOS is present. Additionally, your husband should undergo a semen analysis, as fertility involves both partners. Please schedule a comprehensive fertility workup to determine the safest and most effective treatment plan for you.
