Period

Shelby

So I've been using this app because I'm wanting to get pregnant. I logged my period in and normal it only last 7 days well yesterday I got off of it I wasnt bleeding all day yesterday all of a sudden I started bleeding again out of no where but it's like a light color bleeding and it's about moderate not light but not heavy. This app said I ovulate from the 21-27th is it normal to have a bleeding day after your period ends?
