Those of you who have been successful in conceiving with this app, what day(s) did you have intercourse? This app gives 4 or 5 'green' days and I don't know what day is best, or to just try on all of them? I have endometriosis and I want a baby so bad. We have been trying for over 2 years now. This is my second cycle using this app, so I'm still trying to work my way around it. Any advice and tips are more than welcome!
