I didn't learn about NFP until after my son was born. He's almost a year now. I'm still breastfeeding and haven't had a period or any inkling that one is coming. I do have mucus, I don't really know if it's the fertile kind or not. I've had it for a long time and it doesn't seem to change. I've read all the descriptions and everything, but I didn't learn to pay attention to my body until after I became a mom, so I don't have any experience to look back on of what is normal for me. Can I pretty much count on being infertile until I have a period? I know there's a chance of ovulating before menstration returns, but isn't that pretty uncommon? My boy still nurses often throughout the day and night. Anybody more experienced than me with advice of if I need to break out the condoms or not?
