I’m worried

So I’m a little worried, and confused. I got off the nexaplanon on July 3rd has my period July 3rd also, has my period August 3rd and this is the first month I’m testing for opk... I got a positive ovulation test lastnight so does that mean I’m actually ovulating or will it take awhile for me to start ovulating normally after getting off the birth control. ? This might sound dumb but I’m new to all of this.
