After one month of using glow to help track out cycle- during my second cycle Glo helped us time my peak ovulation and we got pregnant that cycle! It's a miracle it happened so quickly! We were trying w a fertility specialist for a year before and no pregnancy happened except one which was a chemical one. Glo was easy to use And my partner had the app to so we could be on the same page. Would recommend trying! Timing has to be perfect and Glo can help! Thanks Glo!
