I've been using Glow for 3 months now. I was pregnant with twin boys two years ago and had a miscarriage at 20 weeks. It was the worst feeling ever. I decided I was ready to try again and thought about trying Glow. I tracked everything with this wonderful app and when I noticed I was a couple days late I decided to take a test. I got a positive. Husband and I are beyond ecstatic and can't wait. Thank you Glow!!!
