I got a slightly darker positive yesterday, here are the tests from yesterday (mid morning) and today (same time). I tried to do one last night but we’d gone out to dinner and it was too diluted so it showed negative. Anyway, according to these tests do you think I’m ovulating today, or tomorrow? I had a little lower back pain yesterday but no ovary pain yet which I do usually feel. I’m so worried we’re going to miss it, we bd’d Friday night, last night and this morning, too! PS. These tests have the control on the left, test on the right.
