Hi, so I was wondering if any of you know..

If I start tracking my fertility with e.g. Natural Cycles app and know exactly when Im fertile, that must mean that there is no need for my boyfriend to pull out when Im not fertile, right?

I hope it makes sense. I really dont want any hormonal or copper birth control, but still dont want to keep using condoms every time..

Sorry for the long post and thank you in advance :)
