[sudo-discuss] was there a post a long time ago about 'hack your period'?

I just found out that avoiding pregnancy via rhythm method is pretty reliable and not even hard to do considering there are 250 apps to help you do it. HOWEVER, this app is asking me questions I don't know the answers to - how do you tell where your cervix is? is cervical fluid different than the regular goo that comes out of my vagina? how do I tell my temperature? Did the non- annoying period app ever get made? now that I understand what it's for, I am interested in helping on this project. I'm using ovuline mostly. I like the interface, although I am annoyed that ALL PERIOD APPS (except two) assume (1) I am a woman, (2) I am trying to GET pregnant instead of trying to AVOID getting pregnant. Check out "MyGirls," it is a very amazing cultural artifact made by two Russian physics graduate students in washington state. It assumes users are men.
