Ovulating ????

So since my miscarriage I never know what's going on . I thought I was late on my period so I kept raking test after test and they were negative . Which was fine but I didn't understand why I was so late and then I felt like I was ovulating again . So I took an ovulation test just trying to get some answers and this is what I got . Sooo I guess I'm ovulating and my period isn't coming any time soon ? The darker line is the actual test line . Who else takes these should I be having sex .
