Me and my husband are trying to have a baby we have three trying for our last one but I misccared back in June and had a period on augst 3 through the 7th and ovultaion test already said positive yesterday one day after my period ended why would I already be ovulating??

One to thing be sure of with ovulation kits is that the line is as dark or darker than the control line. A faint or light line works with a pregnancy test, but not with an ovulation test. You will usually see some line throughout your cycle.

It can be possible that you are going to ovulate early... some women naturally do, sometimes it happens on an off cycle.
