Has anyone been successful with this app?

Ever since I started using this app, it's just been an added stress to an already stressful time. Plus I think the app has "learned" my body better than I have and at this point as it's getting close to my hopefully missed period instead of suggesting I test, it's now telling me to get more ovulation kits....I just want some positive results and to hear that other successful married women have used this app and gotten pregnant!
