Its my second month doing opks. Last month i only took them once a day at 2. And i never got a surge. Or really even a line for that matter. I have a regular cycle, so I'm going to assume I should ovulate regularly but I started talking them earlier than what my app says (actually both apps, they say differently) I took two yesterday and the line was there but not positive. Today i just took one and it's lighter than yesterday's tests. Does that mean I already ovulated or should it still be coming?
