After a miscarriage, it is common to have mild lower abdominal pain for a few days as the uterus returns to normal, but ongoing pain can sometimes mean that some tissue is still left inside (incomplete miscarriage) or there is an infection. Even if you prefer not to visit a gynaecologist, it is very important at least to get an ultrasound done to make sure everything is clear and safe. For now, you can take rest, stay hydrated, and use a mild pain reliever like Paracetamol if needed. Avoid using any strong medicines or home remedies on your own. If you develop fever, foul-smelling discharge, heavy bleeding again, or severe pain, seek medical care immediately, as these can be warning signs that need prompt treatment.
