Your safety is most important. Please book an appointment with a gynecologist immediately instead of trying anything at home. Only a doctor can advise the correct, safe procedure.
This is a serious medical thing, please do not search for methods online. Complications can be severe. Immediately consult your doctor to do this safely.
I understand you must be going through a very stressful and overwhelming time right now. Please prioritize your health and visit a gynac. Doing this without a doctor's supervision is not safe at all.
