We have been trying for 7 months to have a child by just leaving it to chance but I was tired of being disappointed every month, this is when I sought the help of glow, I filled in my details and from the word go they were really accurate in their calculations (I even used clear blue digital ovulation stick to make sure the timing was right to my surprise it was perfect to the day!!!) I used some sperm friendly gel and my husband and I did it on my 2 most fertile days and in our first month tracking I am now pregnant!! I am sooo happy and wish I had tracked earlier! Thanks glow for a wonderful app :)
