Hi i'm 20 years old female i'm trying to conceive. My periods was on 3rd june and again I got my periods on 17th june but this mid cycle bleeding was different like 1st day some spotting and second day heavy bleeding and 3rd day little brown discharge and my periods stopped [so basically heavy bleeding was on 2nd day and the color was red ]. And the bleeding was not painful like regular periods . So this can be implantation bleeding ?
