Ovulation tests

I'm new to the ovulation test world the bottom test is from Wednesday and it goes all the way to this morning . So is it safe to say that I ovulated yesterday ? I had extremely bad pains (always got them and always figured it was from ovulation but this is the first time I've done the tests I also have endometrisios) we BD'ed everyday of these results just in case ! My husband and I are trying so hard to have our rainbow we've had 2 losses any advice or stories about opk would be awesome !!!
