Thoughts on Natural Family Planning?

Hello lovely people! A little backstory - I have had the IUD (Kyleena) for 8-9 months now. I really don’t like it (my period is 2 weeks, low libido, bad cramps etc.) I want to get it taken out but I am not sure what to do birth control wise. I was on the pill before I got the IUD for 5 years. I just got tired of taking a pill every day at the same time and having hormones run all around my body lol. Before that I tried NuvaRing and it wasn’t great (mental health side effects). I am engaged, so I am only with one partner. I would love to hear people’s experiences with natural family planning/tracking your cycle!!! Thank you :)
