I grew up catholic but strayed for awhile. My fiance and I have a 1yo and I'm currently pregnant. We are getting married shortly after this baby is born and I would like to not return to birth control. I've been reading about the different NFP methods and I guess I'm pretty confused. After birth my periods might be irregular (obviously) and I can't afford a monitor or a teacher. Can someone explain what method you use and how it's done? If it's billings or anything that uses cervical mucus can you explain what the different types of mucus are or how to tell the difference between cervical mucus and sperm? I've never been good at knowing my own body and I also don't wake up at the same time everyday. We have a small 2 bedroom house so 2 under 2 is plenty for now.
