ovulation tests

Hi ladies! It's my first time posting and my husband and I are on our 3rd cycle. I thought I would try some ovulation strips this cycle to hopefully increase our chances. I'm only on day 7 of my 28 day cycle but decided to try an ovulation test when I received them today. It looks almost positive already. I'll test again tonight and tomorrow to make sure but is it odd to be this dark already. Glow doesn't have me ovulating for another week!
