Ovulation? Positive OPK?

Hi guys! I changed the coloring of the pictures so we could see the saturation of test line vs control line. I labeled them to make life easy. My tests are from yesterday. My test lines today have gone from light to lighter today, so I'm starting to think it was my positive. That's what happened last month my positive opk only lasted a short amount of time. Trying to get my date right for ovulation as I miscarried last month, and we decided to try again right away. Thanks everyone!
