Glow really helped us with the accuracy of tracking our ovulation time. We had been trying unsuccessfully for 3 monthsuntil I found the <a href="https://play.google.com/store/apps/details?id=com.glow.android">Glow app</a> in September. Glow knew exactly when my period would start, I was shocked with its accuracy. After realizing I needed to become more active with my logging, we finally missed our period on December 22nd! I waited until Christmas Day and surprised my husband with the pregnancy test and a homemade card that said" Merry Christmas Baby!" He knew exactly what it meant. He was shocked because he knew that my period was suppose to be on so I had to plant tn pons in the trash to throw him off. Thank you so much Glow!!!
