We use the withdrawal method. I was using a diaphragm for quite awhile as well, but now just withdrawal. I "loosely" track my cycles by just monitoring when I have my period & writing down how my body feels throughout my cycle. I've been able to keep track of when I'm ovulating just by doing that.
We use the withdrawal method because I react rubbish to hormonal contraception and don't really want artificial stuff in my body anyway, it has worked for us for 2 years I'm fed up of getting the lecture off my friends though about sperm in pre-cum it's like don't be so quick to judge and do your research people! I try my best to enlighten them but I can see some of them think I'm talking garbage.
I use iyoni app to track my fertile days (they are very accurate) and we used to use the withdrawal method
Have you considered maybe getting an IUD like Paragard? I am planning to get it done here in the next couple weeks. It's hormone free and it can be removed at any time. I believe it can last up to 10 years? I will let you know how it goes when I get it done. As for condoms, yeah they totally suck. Really REALLY hate them and so does my bf. Sometimes they even break and that is even worse lol. They always ruin the mood when he has to put one on. Same for the pull out method, that one sucks as well. I mean nobody want's to pull out in the throws of things, just ruins the passion. Also, I use Fertility Friend to track my periods. I haven't really tried the other apps.
