Ovulation testing

So I've been taking first response tests. I recently had my IUD taken out and had a lot of bleeding which wasn't sure ugh that was my period or not. I know the second line needs to be as dark or darker than the test line, but my question is, does this mean I'm going to be ovulating soon? Or does it always have two lines no matter what ? the line is a little darker to the eye than what my camera picked up.
