Fertility awareness methods (FAM) and period like cramps

I had been on PoP contraceptive pill for nearly 10yrs, I have also tried CoC's and injection prior. I wanted to learn more about my body and be natural. This method takes a lot of research and understanding in order for it to work and be effective. I read books and watched YouTube videos to educate myself and joined FB/Reddit group. I use an app called read your body to input my temperature and other symptoms to track where I am in my cycle. It is all done manually by me and not relying on a system like natural cycles to do it for me as this is less reliable....Since stopping the pill my libido came back which is great and I feel emotions depending on where I am in my cycle. My Cycle regulated within 2 months after stopping the pill and for the past 3 years I have learned what is normal for me. My cycle is very text book 28 days long on the dot every month, I ovulate on day 15. This method works for me, I haven't gotten pregnant but on the days during my cycle I could get pregnant, we use condoms rather than abstaining. I would say it took me about 6 months to learn and feel confident in this approach.

First few months lots of ‘red’ days (no unprotected sex days). Coming off the pill was a personal choice and brought back lots of issues i.e needing prescription pain medication. However, my sex drive and mental health have significantly improved and impacted on my relationship. I’ve used natural cycles for 2 years religiously and no problems or pregnancy.

You have to take your temperature and do a ovulation test ( wee sample ) both in the morning then you add all in the app and it tells you if is a red day ( which you have to use another contraceptive method ) o green then you can have sex without contraception because when you have a green day you are not meant to get pregnant . I think if you want to get pregnant go for this app ! but as contraception is not very good as you hardly ever get green days and when you get them ( very rare ) you feel you can still getting pregnant also boyfriends / partners find so difficult to trust the app which it makes it even more difficult for the woman . As an app works very well and is interesting to know when do you ovulate or if you don't ovulate or if you ovulate twice but as contraception needs improvement
