It will subside in a couple of week. In case the symptoms persists, there is fever, foul smelling discharge then one should consider removal of coil. These symptoms are unlikely to be due to pills In case you need any further assistance, will be glad to assist you. Wishing you happy and healthy lifetime Care Best Regards Chat Doctor.  </s>
