NFP advice

Jazmin • 21 | Mama & wifey
So I decided the best choice of birth control for me is Natural Family Planning. Tired of all these hormones in my body. I recently started losing A LOT of hair due to the depo shot & actually seeing what it's doing to my body made me feel so disgusted. Just got my shot in October & should be going back in January but I'm not getting it anymore. Husband is backing me up on this plan. I'm nervous and completely new at this. Any advice/ past experiences from anyone that tried this method?
