Ovulation tests

Mary

This may not be the right group to post this in but I have a question about ovulation tests. If I got a positive today does that mean I wont ovulate for another 24-48 hours or could I ovulate today? My husband and I BD'd on day 11, 13 (yesterday) and day 14 (today) of my cycle. We will not get an opportunity to BD again this week due to me working night shift. I've noticed some pelvic cramps which I assume is ovulation pain. Glow shows my most fertile day to be tomorrow but I'm not sure.
