Weve used this app for 13 months trying to get pregnant. Hasnt worked so far-so, were using a thermometer and tracking basil temps that way.
Its got a great layout. But if youre trying stick to the old fashioned way. All the apps just spit out different dates for your fertile days and you may go crazy.
