Having 3-4 miscarriages with heavy periods can be very distressing, and even if routine reports are normal, there may still be underlying causes such as hormonal imbalance, subtle uterine issues, clotting disorders, thyroid problems, or conditions like endometriosis, which your doctor may be trying to manage with Endosis. However, Endosis is usually used to control endometriosis and not directly to help conception. The next step is a more focused evaluation for recurrent pregnancy loss, which may include specialised blood tests (for antiphospholipid syndrome, hormones), detailed ultrasound or hysteroscopy to check the uterus, and sometimes genetic testing for both partners. It is important to follow up with a gynaecologist or fertility specialist who can guide targeted treatment, which may include hormonal support, blood thinners, or assisted reproductive options, depending on the cause. Try to maintain a healthy lifestyle, manage stress, and take folic acid, but most importantly, continue care with a specialist to improve your chances of a successful pregnancy.
