My period due date was 17th oct still I started bleeding from 6th oct and it continued for almost 10 days although it was more of spotting kind of bleeding except 1-2 days when it bleeded like normal periods . I thought maybe it was some early arrival of period thing and also after 16th oct bleeding stopped but today again bleeding started so now I'm confused whether it's a normal thing where I'm having periods twice in the same month (which has happened with me only once during teenage) or is it something serious to be worried about? What should I do? Also I'm not on any kind of medication and I'm sexually inactive. Please help
