I have been trying to have baby for 10months. At the time in Nov I was really disappointed and begin to doubt myself.  Then I happened to know Glow from an IT magazine. I can't believe that I succeed in only One period. Girls I never comment app with 5 stars but Glow Reach all stars and I really want to thank you. In China not easy to know good English apps. I will share Glow with friend who wants to have baby.
