I only tried to get pregnant for three months. It was very important to us to not have our daughter be an only child since both my husband and I have many siblings. The fertile days are right on with this app and I do believe my decrease in caffeine intake helped a lot. I was a big soda drinker but my neurologist said to lay off due to me having migraines. What a blessing God has allowed us to have. Thanks Glow for the guidance!!!
