Kinda new to this...

Hope
I'm trying to conceive. After a couple months of negative tests, I decided to try the ovulation test kit. All week long I have had "high fertility" but no ovulation. I didn't think you stayed fertile for that long? And I'm not sure if that means I'm just not ovulating or what. Is that normal? I started these tests Monday, and took one again this morning. Granted Monday's came back a blank circle meaning low fertility....but since then it has been high. So do I just keep taking them? I'm very new to this lol.
