First time ovulation testing

Hi all... so this is the first cycle that I've done OPK's. More than anything I wanted to make sure I'm ovulating in general. I'm using the dip stick tests. I tested once a day since last Thursday (cycle day 10). From Saturday through Monday one line was slightly lighter than the other. Finally got two same colored lines on Tuesday night, and again yesterday-yay! Today one line is lighter than the other again. Does this mean I'm done ovulating? My apologies if this is a dumb question, but I'm a newbie! Thanks in advance, and baby dust to all! :-)
