So I'm about 6 weeks PP and I purchased ovulation tests, NOT because I want to get pregnant just yet but so I can know when to expect my first period and when to avoid sex as I'm not on birth control yet. My question is, do these lines mean I could be ovulating soon? The first one is 2 days ago, second one is yesterday and bottom one is today. So it seems like they're getting darker every day? But I've never taken them before so I'm not quite sure how it works
