I tested and CD 13- CD 15 and CD 14 I got a smiley face on the digital test but unfortunately the hubby is a blue collar guy and he was out of town that day and didn’t come back until CD 15. Did I miss my chance this month? Every test I’ve taken after CD 15 the lines are not very dark and the T line is barely showing up at all. This is my first time <a href="https://play.google.com/store/apps/details?id=com.glow.android">tracking ovulation</a> with the digital test strips.
