Help please ):

Okay so ! In between all this I was having that white thin discharge(heavy) . 9 dpo I had some faint cramping and the single brown streak of blood . 12 dpo and day before period I started bleeding and cramping and now 13 dpo still going on . I feel so positive I’m pregnant but everyone tells me you can’t bleed and be pregnant . I’m having soooooo many symptoms and never had before . Is it possible to have ib and then have a period and still be pregnant?
