Hello Thanks for writing to us with your health concern. Regarding irregular cycles, it should definitely be investigated. If not investigated and properly treated, it can lead to issues in your overall health and specifically for conception . I suspect you would be having PCOS - polycystic ovarian syndrome. It is a condition of basic hormonal imbalance - the ovary is studded with multiple follicles ( resembling cysts ). None of these follicles mature to form an egg, so ovulation is unpredictable, and cycles are irregular. Apart from oral contraceptive hormonal pills ( like Lutera ) other medications can be taken to control PCOS. These include Metformin, which will help to regulate cycles. Also, if you are overweight, try and lose weight, it will also have a positive impact on your cycles. A proper workup for irregular cycles is necessary. This will include a thorough internal check up - per vaginum and per speculum. Also a pelvic transvaginal ultrasound scan, and hormonal tests - FSH, LH, TSH, prolactin, OGTT, DHEAS, free testosterone, Lipid Profile. TVS is absolutely safe and ultrasound involves no radiation. Also, Trapid MF is a safe drug for you. All the best.
