Hi! First time using this kit. I've been struggling for a few months to find my exact ovulation days, so I decided to buy this kit and see if it would be easier. Today was my first try and I am on my day 13 of the cycle. Yesterday I took a Clearblue digital ovulation test and came back negative. What do you think about the lines in the pic? they are pretty close, but not sure if they are positive. Please help! Thanks ☺🙏🏻
