Ovulation Confusion

Mariah
Okay ladies, here's a little bit of a back story. My husband and I recently went through a miscarriage at 9 weeks this past December after ttc for about a year. I had a cycle is January that was horrible, then my cycle this month on the 6-10th was normal. I decided to take an ovulation test yesterday just our of curiosity. I have a 27 day cycle so my question is, why would I be ovulating on CD 7? Top 2 are yesterday, bottom is today. Thanks ladies!
