I am 38 years old. We have been ttc my 3rd child for 7 months. Our son is 14, daughter soon to be 4 and wanted to grow our family. We were trying since last year! I have a short 23-25 day cycle. This is the first month I used your app. The app I used before predicted my ovulation a week after your date. I went with your info and first month with you....I'm pregnant!!! Thank you SO much.
