Odd change

Since last week ive been bleeding (ill say bleeding because i dont know what else to call it) its not blood tho its brownish and at first I thought it was discharge. But its been going on for a week which has never happened before to me it started when glow said my ovulation would start. Ive been a little worried but I googled it and it says it could just be mid cycle bleeding but today I bleed a lot and its very red. Im just wondering if this has happened before to any of you. Im a little worried I just want some insight on other experiences.
